Familiarity: I've used it several times
I really like how versatile this is. I'm glad it was my first choice and I've never looked back.
The deep V notches in the brake add a little too much friction on rappels, but they're great for belaying. This isn't really a problem since the manual says you can run your rope out either direction when rapping. I guess it's more of a preference thing. I suppose there's a chance I might run my rope out the high friction side if I weighed more.
I love the extra ring, and am all together stoked on this piece of gear.
