Less friction, causing problems?

MTS247 · 12th March 2009, 06:14 PM

Has anyone else noticed that your friction hitch has to work alot harder when using rope guide or similar? I would imagine that the reduction in friction means that the friction hitch has alot more weight on it.
Also the old prussic loop seems to perform very poorly when using a rope guide or similar low friction set up.
Anyone found any ways to improve their VT?

Suits me fat ass just fine, reduction of friction atop means more at the hitch, better bite but a biarch to unlock a frozen hitch.

I do a 5 turn blakes, no worries, tail goes through 3rd turn not second.

Your VT will perform very different on a pulley compared to over a limb.

It needs to be tuned to suit. Play with lengths & coils up & plaits down to get what works best on what you use most. It wil also vary lots between different types of cord too.

Ive used the VT on a pulley since 97 no probs.

Once you get it right you'll love it and think it sucks when you are just over a branch!

Got a pic of your set up?

Dont get me wrong i like the rope guide and anythink that makes climbing easier, just noticed it gets a bit tight sometimes.

Anyone tryed using a micro pully for the small side of a cambium saver and a auto locking revolver as the big side of the cambium saver. this should provide similar friction as a rope guide but is very simple to install from the ground.

I'v seen them with a pully in one side.

Or using a pully on each side of a cambium saver, as long as one is big enough to catch the "ART retrieval ball" and the other small enough to let it through.

Im sure its been done.
