CE has a newer rating chart DIY, CE 350 is what is called for with his rig at 65#'s and 28.5 length. Which CE's are you using wooden? Also which nochs and fletching as well as anything else to add in for weight. Need to know the total weight of the arrow to figure out an estimated speed. Even with my bows that throw a hunting rig at 320fps I still don't shoot past 40 yards on live game. Just my limit. If you are limiting yourself to 40 yards and have a relative speed of 300 to 310fps then I personally would set a 3 pin up to 20-30-40. From 0-20 the drop is negligible, from 20-30 the difference would only be around 2 -4 inches at best according to what fletchings you have and what setting you have them at, I.E. Straight, offset, helical. and then another 2-4 inches from 30-40 again according to your setup. One of my rigs I just use a single pin out to 40 yards. But that puppy smokes my hunting rigs out at 336fps with 1 degree offset fletch. with only 6 inches of drop from 0-40 and I know that setup like the back of my hand so I know my holdovers at 40 if needed.
