to get back to the original question.....i sometimes use the nugent blade which is a two blade cut on contact head so should i rip one fletching off and only use two fletches because i have only two blades? come on now?!? or i also go hunting for wild boar and use the steelforce 150 gr. hellfire which has four blades and is cut on contact, maybe i should change my whole arrow and add a fletch. come on now?!? but with common sense here i mostly use NAP thunderhead 100 gr. 3-blade and of all the 23 deer i have shot with that set up they didn't care and it didn't matter whether the blades were lined up with the fletches, all 23 are either in the freezer or on the wall.....
