i shoot split finger, and when i built my sisters bow i designed it asymetrically so the top limb is an inch longer than the bottom one. the neck of the grip and where you nock the arrow are about dead center of the bow, with the arrow pass being just about 1 inch above that. its the closest ive been able to get to the arrow being truly centered, and the bow was absolutely the best shooter i made so far. i think this design ultimately allows the bottom limb to have more working area than the traditional layout, as you are gripping less of the lower limb in the end.
