The sad thing is, he's probably serious. Just amazes me the misinformation and the levels of bad arrow flight some people will accept. The problem of course is not with this hunter but with the education and professionalism at the point of sale. My pro shop wouldn't let you walk out with your first bow without thoroughly educating you and giving you a set of standards that would make you answer all these questions yourself. They would tune you to knowing what good arrow flight is, why you need it and how to achieve it. Then the question of fixed or mechanical would be answered by personnal preference and the equipment of choice(poundage/K.E.)
