yeah thats true, but i haven't cut the arrows yet. so before i have to turn back the bow i was trying to see what info i could get. i found some thing on-line that i tried to get a number for my foc, but it didn't a 2" blazer option... hence why i asked the question. guess i should just do it and if it doesn't work back the bow down... Or could i just drop down the broadhead to 85gr. to make it work?
