Ed, my goal is to get in at about 10 lbs, maybe 11. I have on hand the Edge540 26cc from Peak. It is supposed to weigh 4 kilos with the SPE 26 and my MVVS is about 400 grams more because of the tuned pipe. I think I will stay just under 5 kilos and have about 8-9 kilos of pull. That should be fun! I will not maiden it until next spring because winter is bad around here
