I have always been partial to Tru Ball releases and this year they came out with a few new designs. I just picked up the Tru Ball copperhead and its a heck of a release! Very small, and it uses a web strap connection to the wrist strap so you can make it as short as you'd like. Its a dual caliper release and my favorite feature of the Tru ball's is the fact that you squeeze to open the jaws and let to to close them. You don't have to push the trigger forward to close them like most other designs.
I am very impressed with these releases to say the least.
