The 2X2 is too small, and the 2.3 is too heavy for a stock DA. They come in at 18-19 pounds. and forget about putting smoke on it if you want performance. However, with a tuned pipe and a broken in engine tuned for all out performance with at least a 23X8, preferably 24X8, they perform pretty good. IMO, these composite planes aren't the best you can get until you get to 35% or larger.
