RE: Picking a release
Here is my $.02
I would not recommend buying a new release the same day you buy a new bow.
Reasons:
1. You have no idea what release suits you best
2. You dont really have any idea about rollover points, valley, or any of that technical stuff from a release shooters standpoint. Both bows you mentioned are high speed, which means the are finicky.
3. If you havent shot a release, you will, in all likelyhood, be punching the trigger. You must remember, it is actually the back muscles that should trigger your release, not your thumb or forefinger.
4. In that time you are taking to get used to the bow, maybe try one or two releases a week. Dont shoot them too much, just get a feel for it, and its trigger style, and take notes! Lots and lots of notes, so you can remember when it comes time to purchase a release.
Kudos onbuying a new bow, but make sure you do things properly and take the time to get used to the bow before you changetwo factors of your shooting at one time.
Trust me, I know from experience
