have to add there are alot of bad mechanicals out there just like there are bad fixed. i dont include these in my opinions i dont use them. stick to a 1.5" cut or less and a good solid design (rocket steelheads) and ill put them up against anything anyone else shoots. why bother with all the fuss, shoot field tips all year and then when season gets close have to do so much to retune. if your tuned properly already you should be able to just throw a good mechanical on and shoot exactly the same.
