I am sure there will be lots to chime in with way more knowledge than I have, but here is what I have found out since taking up this a year ago.as far as fletchings go, especially the shapes, I haven’t a clue as I use what I like. The Wings, I gather, make no diff either as long as all are the same on the same arrow(be pretty hard to do otherwise since attaching tools are wing specific). My biggest thing is the noise of the actual feather. I have read they make a noise, but the string is going to jump the critter anyway so again, I just go for what I like. Shot placement is gonna feed ya, feather and string noise will not starve ya.
