I have an Mvvs 26cc with an ES composites tuned pipe in the older heavier wild hare edge 120, and it is a brilliant plane.
It will prop hang, but it is on the limit. the all up weight at the minute is 12.5lbs. I reacon if you can get it down to 11 or less your on a winner.
I would definatley have a look at the newer lighter version of the edge, it could only be better.
