BT helps alot of archers....I started out target shooting with guns from the age of 4 and archery at 8. My Paps always told me DONT PULL THE TRIGGER, SQUEEZE SLOWLY!!!! I was so engrained in my mind with SQUEEZE SLOWLY, when I went to my Grip style caliper that has an index finger trigger, it was automatic for me. I cant shoot a BT or thumb worth a crap. Most would look at me crosseyed if they saw me shoot a pistol.
