I was until my elbows got bad, would draw with two fingers and hold and shoot with one. I did buy a release that would be good for finger shooters, you pull and hold trigger through the draw and relax to shoot.
I shot with 3 fingers when the compound bows were longer. As they got shorter, it pinched too much. I switched to a release and was happy. Old age and hurting shoulder have come upon me and the crossbow is better still.
I shoot compounds with a release but I do practice every so often with fingers only just in case I forget, lose or break my release. I was actually wondering if anyone else that uses releases practices with fingers in case something like that happens.
Shot my first 2 compounds with fingers,no sights or kissers. They both shot around 240 fps. Bought a bowtech blackout that shoots 335fps. It came with all the bells and whistles,had to relearn how to shoot . that much speed made impossible to release with fingers fast enough to not affect shot.
I like retro and vintage stuff; as an example, I plan on toting a Savage 99 to Africa soon.
Finger shooting and compounds... I have a very good condition Bear Whitetail Hunter (the powder coated green and black camo), decked out with an age appropriate sight and quiver. I shoot feather fletched green 2016s out of it and, obviously, shoot it with fingers (leather shooting tab). I don't pull it out as often as I should but was shooting it just last week. Fun stuff!
