I shoot a 55lb @ 28 Damon Howatt Hunter. I draw it about 27 1/2". I would like to try a carbon arrow and have heard that the CX terminaters are very good shafts. Would the 45/60's be too stiff? Also, How much weight up front do you think I wou7ld need to get them to tune? I would like to end up with about a 500-525gr arrow. Thanks
