I am currently shooting a medium aluminum arrow and have some smaller diameter carbons as well, Right now I have my prong rest on for the carbons as they will more than likely be the ones in hunting with this season. I have a WB but its for medium arrows, such as my 2314s, should I use a smaller WB or stick with the medium, my pro shop said the medium will work just fine but I am having second thoughts, Im afraid to shoot through the medium incaseI end up really screwing up. Hopefully some of you vetran carbon shooters can shed some light on this and help me out. this is the first year ill be using carbons. Im shooting the Easton Excell ST 400's with 100 grain tip and bh.
