Thank you 10pt... Interesting... I was told by one archery tech that " no matter what anyone tells you DO NOT USE MECHANICAL ( he specifically cited Rage broadheads ) BROADHEADS as the would deploy early with crossbows and ruin the accuracy. Not trying to argue or debate, just confusing when one gets conflicting advice. BUT you obviously know more about Ten Point crossbows than he. What grain Spitfires and what configuration of blades etc.? And what do you guys think of the Slick Trick broadheads?
