Some people are weird and their setups will swerve w-a-y off from the norm. For example, I used to know a left handed fingers shooter who - especially after a few beers - would shoot a right handed bow left handed. He'd turn his string hand OUT, away from his face, anchor with the big knuckle on the back of his hand and he could flat wear out a target that way. I think you could say he was a tad 'unconventional.'

Normal people will need to set up as Bulzeye described. After that, centershot will be adjusted to fit your unique shooting release characteristics. I'd recommend sticking to rests actually designed to be shot with fingers. I've heard of people using whackey baskets with fingers, but I'd have to see it to believe it. As for dropaways, I don't see the point. A regular flipper rest does exactly the same job and is usually less expensive, less trouble to get set right and more dependable.
