I was just wondering about that and posted in the techinal forum about it. I have 4" vanes on some Beman ICS arrows that are getten torn to pieces by the WB on the Parker I just bought. I want the same setup arrows, but how much of a difference does 2" vanes make in relation to 4" vanes other than damage? Better or worse? I'm waiting to click on the purchase button, just need the advice to do it.
