I have a trykon xl and I shoot 67 pounds with carbon express 3d select 300's, and I use a schaffer drop away rest. I set the cam rotation so that my top cam is just slightly faster than the bottom one and it took me 2 shots to get a bullet hole. Also I set up center shot so the the arrow is just of right center of the stabilizer when looking down on the bow from above while resting it on my foot. I work part time at a pro shop and the owner is a national champion and he always sets his bows up like this as something about the top cam being slightly faster makes the bow perform better. I'm sure that everyone might not share this theory, so please note this is just our opionion. Try what works for you. If your top cam is slower than the bottom, just take some twists out of the buss cable tospeed it up a little, and if it is over rotated, just add some twist to the busscable to slow it down some. Hope this helps.
