someone posted that the setup for their ultra-tec was "with a 7/8's distance from the riser to arrow's center". How do you measure that? I have a centerrest measuring tool that marks the center of the string and then you bring the rod forward to adjust the rest with an arrow on it. I shoot fingers and seem to do best when the arrow is about 1/8" to the left of center of the string at about 12 inches from the riser, shooting right handed, 60# at 30"draw and 2413 31"arrows. Does anyone have a better suggestion?
