Ok got a quick question about carbon arrows. Im currently shooting easton XX78 in a 2315 shaft. My question is if i switch to a skinner arrow in a carbo all im going to need to adjust is the rest correct? and resight it in?

Yes on both counts. The smaller diameter carbon arrow will effect center shot and nock set height. The reduced weight of the carbon will require sight adjustment. I prefer the aluminum arrow for hunting and target shooting.
