Ripcord or ultrarest. Take your pick. Both dropaways that completly capture the shaft. Ive also heard good things about the kazaway but it has a lot more parts. If it were me though I wouldnt fingershoot at an animal with a bow that was sighted in with a release. Since the rest position on a finger shooters bow should be completly different than a release shooters. Never even tried so im not sure but id bet the point of impact would not be the same.
