My arrows turned out to be 3555's. By Gold Tip's chart, with a 75 grain head, I am shooting 9-10 pounds over what they reccommend. I have been shooting these arrows for about five years. I originally bought them for another bow that had a soft cam. I also shot less poundage with that bow because it only had 65% letoff. I never checked them for the new poundage.

My arrows are long for the rest I have. I am going to cut them down to 26 1/8". I am going to drop my poundage back to 60#s and try a 100 grain head and see how they fly. If I don't like the arrow flight, I am going to buy different arrows for the new 100 grain heads. With the new arrow setup, I will have a calculated FOC of 12.6 versus 9.6 with the old setup.Thanks again for everyones help.
