I'm trying to determine what the heaviest grain head is I can use on my shafts without effecting the arrow flight. My current setup is I'm shooting a Hoyt Maxis at 55lbs with 28.5 Carbon Express Maxima shafts and a 85gr head. Sine I don't shoot heavy poundage I opted for a light setup in order to get the most speed.

Could I move up to say a 100gr head and it not be to much for the shafts? Obviously the pins would need to be adjusted but I dont know if the 100gr head is to much for a 250gr shaft.

Thanks in advance.

Joe
