I just switched to 125 grain for the increased FOC and have really noticed better arrow flight/ grouping at longer distances. I started to shoot a somewhat heavier arrow(445gr)w/ the higher FOC and really like it. This may be really novice but thought it was interesting. 27.5 in draw,28 in arrow, 64lb Creed
I shoot 100 gr. because I like the BH that I am using and that's all they come in. Plus, 100 gr. balances well with my setup.
