Where do you measure for Arrow Length? Is it from the end of the nock to the end of the arrow shaft? I shoot a Mathews Q-2 (purchased a month ago) with a 30" draw. I use a C Winn Release and shoot directly off the String. What length arrow would you suggest? I shoot at 58 lbs. and I'm interested in purchasing some new Carbons Arrows for hunting and Spot league. What would you recommend?
