I had the same questions that Stone had about releases and which one was good and what the difference was between a talon head and a caliper head, etc. I had asked Rick James about his opinion and he told me to go with the Ultra Extreme by Tru Ball. I really like the release and have been extremely happy with it. This release is a little on the pricey side ($180), however, I was able to get it off of ebay, new in package and never shot, for $95.
