i have heard of the 900 grain restriction in alaska. just for your information, i went to the local archery shop, and weighed a fiberglass fishing arrow. 725 grains, ready to shoot deer. i would probably remove the fish head, and use an expandable head. sure wouldnt have a problem with energy there boy. i think the 900 grain thing is crazy, but the 400 grain rule is more in line, although i dont think they should impose that on shooters either. if anything, there needs to be a proficentcy test, just to make sure you can shoot your bow. that to me would be more important that a heavier arrow. a heavy arrow in the gut is no better that a light arrow in the gut. no matter how much you polish a volkswagon, it is still a volkswagon.
