JTinaTree,
I'm using something quite similar to your Caritool setup, but I went with a Black Diamond "ice rack" wire-gate 'biner because they have a wide flat back that keep it from rotating in the web of the belt.
It's not hard to one-hand it out of this set-up, just grab the lanyard below the ring with with fingers, thumb the gate aside and presto!
What nags me about this set-up (and you mentioned climbing in crowded trees) every little snaggy branch I climb past finds the gate and clips itself to my saddle. This is most annoying, wastes time and sometime damages small branches I would have prefered to leave alone.
Also, when on rope, your side "D-ring" can get flopped into the wiregate. Then the moment you want to flip your lanyard around and clip in so you can advance your rope, you've got to stop and fiddle your "D-ring" out of your racking 'biner.
All in all, I find it a really good set-up on a removal, where everything I'm climbing is clear around me, but so bothersome on a prune that I'm looking for a way to mount a little swivling dog leash clip on my saddle.
Ekka's big U-hooks dumps are what I want, I NEED A SOURCE YOU AUSSIE SIX SHOOTIN' BASTID! Cool vids Ekka, cripes I could sell those things here if I knew where to get 'em.
And, Yes the saw could fall off Ekka's big hooks if I went inverted, but by the time I'm in any such a position in a tree, I'm doing hand saw work anyway.
And finally, Mike Maas, if you have a chainsaw lanyard with a ring six to ten inches back from your clip in to the saw, it's the easiest thing in the world to just flick the saw away and grab the ring, then rack it, one handed.
Ekka, sweet Ekka, I need a source on those beefy saw hooks, please and thank you.
