Elknut1, I'd say I may have lost a half inch in draw length, probably not even that much. I guess I wouldn't worry about that at all.
The noise factor that was mentioned is something that I,too, thought about, because it does seem louder...to the shooter! We were shooting at deer camp yesterday, and one friend commented on how quiet my bow is. I was surprised, because I thought it was louder with the release. Fellow member Schlaggerman agreed that it still is quiet. The noise I'm hearing as the shooter, is because the release is right next to my ear. That explains what I hear, verus what the non-shooter hears.
I'm using a Tru-Fire Stalker release, but I'd bet that most releases could be used. It just takes a little time getting used to the feel of a slightly different anchor.
