pro and con of rope guide vs. prusik adjust FS

Branched out member
I'm thinking of getting a friction saver (rope and pulley style, not B'ham FS)and was wondering about prussik style vs. the mechanical one.
 
Re: pro and con of rope guide vs. prusik adjust F

If we consider the Rope Guide as the one hundreth percentile in performance then where do any of the other false crotches perform?

The biner/pulley setup in the attachment works pretty well considering the cost of putting one together. I would rate it at about 80% or so.

With a few more pieces this FC could work like the friction hitch rope guide setup.

Not quite John, I dont think that will take up slack by pulling the tail.

I have a few different types, what I came up with is I perfer the RG if I am setting it while in the tree or what Tom is showing if I am setting it from the ground. However the legs on my prusik arent that long, different strokes and all /forum/images/graemlins/smile.gif

i dont mean to hijack the thread, but since the subject of adjustable false crotches has come up, is using two wraps on my friction knot acceptable or should i get a longer cord and make my knot bigger? thanks!

Re: pro and con of rope guide vs. prusik adjust F

Like a 2 wrap prusik or a 1 wrap prusik (girth hitch). What friction hitch are you using?
 
Re: pro and con of rope guide vs. prusik adjust F

i guess its just has one more wrap than a girth hitch. is it too hard to see in that picture?
 
Re: pro and con of rope guide vs. prusik adjust F

Being that short Carl it doesnt need to take up slack by pulling on the tail. To me that is not a real important benefit since I usually set it by hand anyway. Aside from that its virtually the same as the RG in function
 
Re: pro and con of rope guide vs. prusik adjust F

Sizzle-Your Prusik is fine provided it holds okay for you-if not then an extra wrap can increase gripping power.
 
Re: pro and con of rope guide vs. prusik adjust F

Yeah John, the only time it comes in handy is when I am throwing it a bit above me, sometimes it can make a world of difference. However since it can follow the same angle as the rope with slack it really doesnt make too much difference, I can set it above me and not have to take up slack, just let it hang loose. On that note, where did you get the shackle pulley and how much did it cost ya?

Sizzle, I didnt see the attachment, Justin is spot on as usual. 2 wraps should be plenty for taking half the weight, however I usually go with 3, habit I guess.


One thing I would watch out for is that screw link. In some contorted way it is possible for the rope to both contact, unscrew and get out of the screw link which would make for a bad day. It MIGHT be against the almighty ANSI. I would replace that with a biner and be all set. Here is a ring and ring i spliced up. I can take off the ring and replace it with a biner and pulley if I desire.

Tom, I gather that biner/pulley set up can't be removed from the ground...do you use it as a redirect, or what?

When you want to install a rope guide a few feet above your head, is that done the same way with the mechanical RG as the prussik RG, and is it as easy? Or do you have to be within reach of the prussik RG to cinch it up?

If the mechanical RG is a 10 out of 10, what makes it better than the prussik RG?
 
Re: pro and con of rope guide vs. prusik adjust F

The 'made' rg can be removed from the ground in the normal way. Setting it from the ground is a bit harder than a ring on ring FC. I've found that the length of rope below the friction hitch sometimes flops around and snags.

Since I rarely set a FC from the ground any of these complications don't matter. If I knew that I was going to remove the FC from the ground I would consider extending the friction hitch to the stopper knot. Another option, which I've never done, would be to tie up the slack using a hitch like a hangman's noose.

The RG gets a 10 because it is so smooth, can be snugged up a bit higher by pulling on the tail and has a great pulley.
 
Re: pro and con of rope guide vs. prusik adjust F

Tom, You'd have to add small link to the homemade RG to retrieve it from the ground, right?

So is higher cost the only drawback to the mechanical RG over the prussik version?
 
Re: pro and con of rope guide vs. prusik adjust F

Carl, -No worries for Sizzle-screwlinks are more secure than 'biners-especially if they are tightened with a wrench or pliers.
 
Re: pro and con of rope guide vs. prusik adjust F

yes, in fact i cant get it undone without a wrench. and it would take about 10 full turns to open up enough room for the rope to jump out.
 
Re: pro and con of rope guide vs. prusik adjust F

The puilley is also homemade Carl.
Its a twisted clevis(rated) with a pulley sheave over the pin.
And it wont come undone the pin locks in and i also used thread locker. It aint going anywhere.
 
Re: pro and con of rope guide vs. prusik adjust F

But isnt the point of the screw link so you can connect it midline? Seems cumbersome to have to use pliers or a wrench to set it for every tree.

Maybe I shoulda said I perfer a carabiner haha /forum/images/graemlins/grin.gif
 
Re: pro and con of rope guide vs. prusik adjust F

no point in trying to set mid line... the screw link never needs to be removed in the tree (unless you have a very ugly splice in your line).... I have several different versions of the RG, including some that i have made myself, all of these are great (10 times better than a regular friction saver, and 100 times better than running natural crotch), but the newest version of the RG (the one with the scremer) is hands down the best... worth the money! it retrives so much better than some of the other versions, and it is very smooth /forum/images/graemlins/driving.gif

and the traditional friction saver ? 75 % ???
