First, my hat is off to you Sir if you can hit a turkey at 60 yards. I would have trouble hitting a house at that distance. We hunt them in the fall like deer. Some will come into a feeder and some are spot and stalk. I've killed 2 that way and both under 20 yards. Never hunted Maine and things are done differently in different areas. Heck, people scoff at our use of blinds and feeders here in Texas, so no disrespect intended, but I think you gotta get closer to solve the string jumping problem, not speed the arrow up. You'll never get it fast enough IMO.
