Arthur gives good advice, I just have a few other comments. first of all you don't need 2 releases. You buy one quality release and don't drive your truck over itand it will last you for many many years.

Basically I feel itboils down tothe individual and thetype of hunting you do. If you can devote the time to practice and are a good fingers shooter who takes sensible shots, then go for it. But if you don't have the dedication or skill to develope a good fingers shot, or if you get excited easily, or are going to want to extend your range as far as you can, then you should go with a release.
