I agree with the recommendation of Paul at Badger Arrows as well as the AD Hammerheads or Hammerhead Lites. The Grizzly Sticks are good shafts, and I have some of them, but all the AD shafts are great. For your poundage of bows, I would go with the Hammerhead shafts, not the Lites, although the Lites would also work great for most anything you would want to shoot. If you really want your arrows to be nearly bullet proof, use brass inserts and aluminum collars up front as well as uni-bushings and g-nocks at the rear. You will be amazed at how well the arrows fly and how sturdy they are under abuse!
