RE: back tension
True triggerless bt releases are not IMO good hunting releases, and are designed for target applications. Thumbar 3 or 4 finger bt releases can be used for hunting because you can “comand” a shot better, but pulling heavier bow weights with them can be harder.
IMO they are still good to learn and use during the off season as they will teach you much about proper form and shot execution. This can be applied to your wrist strap trigger hunting release.
If you do not want to change releases you can learn back tension with any regular hunting release as long as it has minimal and firm trigger travel.
If you learn how to, and practice often you can still command a perfect shot when hunting. Target panic comes from constant repetition of a bad habit. The brain learns what is coming and reacts to it subconsciously . By practicing properly and occasionally throwing in a few command shots the yipes will not get you.
