The one for tachyon looks pretty close
If you're rope walking in any fashion, you'll have some type of ascender for each foot, so there is redundancy. Also it doesn't take much to setup a 3:1 z rig to advance either, so additional redundancy...
Yes you're slower, but no where near stuck having to decend
The whole reason for vertical speedlines is so you can push a chunk off and have it not bounce, if your aim is good , no need to worry about collateral damage
Not something to use every day or even every month, but for close quarters, it's awesome (use a rigging ring for best results)
Leave the zigzag on the line... Leave the carabineer on the chicane, use another carabineer in the top hole for ddrt and as part of your come for srt so it stays with the zigzag setup line... Get a corner trap carabineer for the harness attachment side of the zigzag
Get 4*8 since most of the lifts can spin around on one pad instead having to use 2... I've also seen the 3*8 pass get wedged into the under carriage before as well
Otherwise unless you're using them on a driveway or in the rain i don't think it makes much difference if they are smooth or textured
Just stumbled across this, anyone have any concerns about the strength of the splice? as it looks like the eye is composed of just the cover, so ~half the strength of a standard double braid splice?
Nugreen's break test video seems to corroborate those rough numbers
my wondering is driven by...
Light mechanical advantage with a pulley in the loop helps some... But it's still less than fun...
Can always do a regular eye and eye and put one of the petzls open rings on it
I've got spare chains that I swap if I destroy one (metal in tree usually) otherwise sharpen by hand as needed. Have 2 climbers and 2 ground saws so I normally wait until one of each is getting dull and do them together while ground crew handles final clean up. But saw doesn't see much use, but...
Most days mine sits in my truck (and by most i'd say 95%) but those days it comes out, it more than pays for itself.
If you do most of your work on spikes, you'll have far less need for it.
1 I think nugreen store, or Treestuff did some break test videos on ultra slings
2 only reason I can think of that prussik aren't more common is the loads they can't take... I.e. they slip under excessive load, so would need to have a stopper knot below it. Also the strength of prison cord is...
The Rock Exotica transporter doesn't have any snaggy bits (and truth be told is slightly better in every way, slightly more gear capacity, slightly bigger opening, easier to operate blindly lock, more secure saddle attachment)
Funny that you mention the lack off handsaw... I too leave it on the ground and purposely go out of my way to climb trees without a lot of dead wood and definitely no hangers, no need to increase my risk, or leave a mess from breaking and tossing hazards... The whole leave no Trace thing from...
Never did anything more with it than the video on the truck. Looked near, but didn't like how it felt in the hand.
Don't get be wrong id still love to see a zigzag mated with a hitch hiker, I just don't think that's the way to do it
