I own 2 Extra 330Ls and they seem to be the best IMAC and 3D plane I have flown. I owned a H9 Edge, and it was ok, but does not compare to the DP Extra 330L I fly now. My FiberClassics 35%is the smoothest flying plane I have EVER flown. I found on the Edges that they like to pitch a lot, whether its in IMAC of 3D, they seem too pitchy. I flew a Carden 40% Edge, and I was fine for IMAC, but I didnt 3D it at all. The H9 Edge has a harrier problem, the wings wont stay level. I dont know why, it may just be the design of that plane. I supposedly have a DP Edge on the way, so we'll see how that flies compared to the Extra. Right now, my vote is for the Extra. I am pondering getting a 39%, and it would not be an Edge. Id prolly get the AW 330L. The DP Edge should be a good plane though, we'll see.
