your guys can't switch from wrapping clockwise to counter clockwise on the porty?

My current guy no. My last two guys yes. But the kink that gets caused by them I run the rope out the other way every other job to cancel the kink when we are ready to flop the trunk.

on a regular porty one can add or remove a wrap, carefully, holding strong with the tail of the rope. I can't see a way you could do this under tension with this jailbreak thing. That seems like a major drawback.

The claim is that no matter the amount of friction, you can feed the rope through if you have too much. I’m interested to hear from users when they get them in the field.

It’s also like asking them to solve a Rubik’s Cube blindfolded. I think I tell him every job but apparently it gets lost in translation. Oh well I’m not the one fighting the kink just waiting.

sounds great. watching a bit of video, I think one could slip the rope off one of the bollards if needed, rope would bounce a bit. but like you say, maybe that isn't as much of an issue as it is with too many wraps.
would be fun to try it out some time.

I dunno guys, call me crazy but we do the alternating wraps and we get hockles still on our Portis. Particular using rigging rings like we like to and when we are going sort of heavy foe the rope (within safe limits of course)

In my imagery
i view the apex of an arc as most responding part of rope to read rope from as seats to host
>>like 'Primary Arc' apex gives best nip as 2\1 pulley force position, directly feeding from input of Standing Part(SPart/in knudeNoggin speak; now standard for years for all at IGKT as a most respected resource)
i view bollard vs. rack as both opposing arc apex friction devices.
.
The bollard tho I see as a radial list of opposing arc180s apexes of continuous direction (Clove too is continuous direction)
the rack contrasts as a linear list of opposing arc apexes in reversing directions counterbalancing twists more(like Cow) AND can lend to non-constant , less thermal building frictions I believe.
The solutions to me compared to source input of SPart DIRECTIONal axis:
The bollard apexes are more on same inline directional axis as input SPart.
To me working more from a capitalize on cosine position.
BUT, the rack apexes are pitched 90degrees to opposite yin/yang paradigm of then capitalizing on sine quantity type model solution to me looking still at source SPart axis direction as the benchmark cosine axis as then see sine as a deflective waveform to extremes off this proposed cosine.
In the end both scales mirror each other to same end math for the 2 strategies.
Also arc is Natural flowing deformity allowing cosine and sine employed at each degree to mostly more external force at that point against host than rope internally carries. Arcs in rope control are that important.
Each friction point of drag you might fight is also a gift of friction buffer to capture 'purchase' of rope from the loaded side to Tailer's side for sweating/swigging.
Just another tool want to incur handle input side, not hammer side of! Choose side wisely. Capitalize on best angle and direction to put your's on it, dance sometimes with it as changes.
For me the math is a language of change comparisons, always trueing senses to. Same senses default use especially in fast moving / sudden decisions necessitated.

Would look to 'paste' arc pressure firmer against host at hotspot of apex for hold?
Jest so ya know i am stealing that
"like asking them to solve a Rubik’s Cube blindfolded"
line, TY!
Frictions to ratio of load, not just linear reduction of set amount.
Zer0 frictions etc.
Segmented friction breaks in rack rather than continuous frictions capstan more effective at expressing Zer0 load rope slip, partially due to impact into rope at single point of no friction vs. Each point of no friction in rack impact able as separate car in train rather than fighting whole train at once. Would think expresses more as elasticity increases . And less back pressure from twists and hockles like from tailer side of friction brake device forming more after capstan than rack.
Reverse turn on bar so that greater pinches lesser after serial reductions?
Tail thru side hole and overhand(s)?
Or after serial reductions to much less and then nip tail under primary arc apex for temp lock, add Overhand for soft lock, another for hard lock as in fig8 lessons type mechanical logic?

TY!
Pic of my mental imagery of bollard/capstan vs. rack for friction reducing arcs by either radial or linear list of arcs, inline or cross axis apexes to source, how linear list of apexes needs conversion to this cross axis, with constant or intermittent friction heats, continuously building torque in rope or not,
As always and all ways view mechanics from greatest response potential (apexes),
direction of input etc. is of full importance,
rigids resist on cross axis, flexibles(rope) don't,
a rigid axis is not only directional but to specific position,
a flexible axis is only directional in that pulling rope downward at side of host or from underneath host gives about same force at the apex (we are reading mechanics from).
In rigids this would give more changes thru structure and to most responding point read.
Thus rigid axis positional as more complicated, flexible axis not/less complicated as just directional.
.
Ancients gifted that all displacements against space/distance or force(antagonistic reciprocal of distance) could be broken down to the measuring scales of directness(cosine) or deflection(sine) to sum all maths of (even potentially)connected elements. These are just measuring scales like a child's ruler only the increments are not even intervals of matching value changes, but rather more logarithmic graduations to read, but just a ruler of simple measurement to read all the same to decode the whys and wherefores of what are looking at.

I don't think that would work as a clove hitch is extremely difficult to undo while under tension. A porty is nice because as long as you fill the barrel with wraps before locking it off, no matter how much weight is on the working end, it can easily be undone. I don't see how that can be done with this and I haven't seen anybody explain how it can.

I test ran one of these for a few months a lil while back. I'm a full time contract climber so It's pros/ cons basically came down to the type of groundies. If they were clever, open minded and willing to experiment they could get the thing to run great. If they were stubborn and unwilling to try to change the way they do things we'd run into problems. If they were mouth breathing knuckle draggers who can't even recognize, let alone run, a regular porta wrap i wouldn't bring it out.
The price seems high until you think about why. Portys are cheap cuz they're mass produced by bigger companies (who are starting to become corporate or corporate owned aka cancer on modern day society that homogenizes and smothers other ethical commerce). Small batch stuff cost more but hopefully is high(er) quality and supports small local economy. Ok, I'll get off my soap box.
Some cons across the board:
Getting the rope tight is a bit of a different process which takes getting used to.
Under wrapping any device is a problem but if the groundie gets scooted across the yard, manages to stop the load and then still can't add a wrap that can cause problems.
They say you can always feed slack if over wrapped but i think they're talking about working with pulleys. If you natural crotch or use rings loads can definitely feel stuck which causes impatient groundies to try to take a wrap off, which can be a bigger problem.
Basically, you got to experiment with it a lil to find the sweet spots. It can dialed in more precisely than a Porty so if you get it then the likely hood of needing to add or remove wraps is less likely.
Anyways, just my 2 cents.
