What kind of bow do you have now?
You can shoot fingers with anything, but your fingers get pinched between the arrow and string when you use a short ATA bow. Mine is 36", and I have some pinch. Some fingers guys like ATA more then 40".

The longer ATA bows will also be, by nature, more forgiving, and I think they may be less prone to torque probs.

One nice thing about fingers for hunting is that as long as you have your bow in your hand and your shooting glove on, you can shoot in mere seconds, without having to first link up your release to the string.
