Could some of you guys that have the software help me out? I picked up a Bowtech Insanity CPXL, 70lbs, 30" draw, shooting a 28" arrow withh 100 gr tips. I plan on shooting ACC Pro Hunters. With my other bow I am shooting ACC Pro Hunter 390's. I'm thinking these are to weak spined for the CPXL and I need to go to a 340 or possibly stiffer. Would anyone care to tell me what the software says? Thanks in advance.

Your CPXL at 70#30" wants a 0.2940 optimal spine.

Best bet for ACC Pro Hunters are 300 spine cut and somewhat good at 28". If work didn't get in the way of things, I would have had an answer earlier today.
