You'll be happier in the long run with the heavy arrows I think. Pushing the envelope can get you in trouble. Trust me, I know. LOL Anyway, I never want to put my equipment through the maximum recommended limits. Especially with these speed bows today. A dry fire is catastropic on these things. I would think the closer you get to it the worse it is for it. Hurray for Washington State having the sense to protect us from ourselves. LOL[8D]
