IMO, every archer should learn to shoot fingers. At least once in thier life.
It really depends on your draw length. Most mfg still make at least one model that is good for finger shooting. The string angle is what gets you. If you shoot less than 28" draw, then 37" ATA would be perfect for fingers, if you shoot more than that, go higher to 40" ATA.
I do shoot a release with modern bows, but a person who is willing to master a good clean release can shoot right with a trigger shooter with good hunting accuracy. But it takes practice. I go by the idea that less is more these days. I went the route of going from a longbow in my childhood to a compound (fingers of course) to trigger, to big a$$ stabilizers, to compound to compound, more and more crap hanging off of it, and now back to longbow. There is something so satisfying with it.
