I shoot only off the shelf, I have a number of the older style bows that have a flat shelf. I solve the problem by using pieces of leather to build the shelf up until I have created a radius, then it is covered by a piece of velcro pyle. The closer the arrow is to my hand, the better my shooting is. However, if you prefer, you may check out 3Rivers archery. They have a lot of stick on rest, and feather rest like the ones used in the old days on those flat shelfed bows.....
