With a +12 swingarm, 14 paddle extremes or staggereds in a 73"RO or bigger or some big 12s or 13s like 76-78" RO. Weighing 270 you could go with a 10 over and some 12,13,14 paddles, 39mm carbs would help you a bit too.I wouldnt buy any small 14s like 68" or 69" rollout, there's a lot of those on Ebay. Hope this helps. Radar
