Best i've used - Petzl SPIRIT EXPRESS Quickdraw Carabiner w/ Sling

I've used these a few times now and they handle like a dream. Super easy to clip and the bone is the perfect amount of stiffness when you need a long reach. The feel is much better than the two previous sets of draws I've owned and I'm glad I finally spent the money on these as I'm sure they'll last many years.
