I've always used 125gr Thunderhead broadheads. Last year I bought a new bow (Hoyt with Cam and 1/2) and switched over to carbons (Goldtip XT Hunter 7595). I did just fine last year killing a mulie and hit a nice bull with the new setup. Last year was more of... set it up, sight it in and go hunt!!! This year I'm trying to get a little more technical. I know some serious techies exist on the forum. I'm curious if "generally" speaking will a 100 gr broadhead fly better or group better than a 125 gr broadhead with the following setup:

28" GoldTip XT Hunter 7595 - 70 lb draw on the Hoyt Cam and 1/2's
