I'm building an Extra right now. The canopy is tray style with four 4-40 screws and two dowels. Pretty straight forward.

It ended up heavier than I was hoping. Estimates: 14 lb with OS1.60FX, 14.5 lb with Moki 1.8, 15.5 lb with DA50. It seems like the Edge's are coming in a tad lighter. Could be luck of the draw too.

I went for the Extra mainly because I like a clean snap entry. Seems like I hear a lot of talk about vague snaps with Edge's. There are still more Extra's being flown in my local area. Edge's are a close second.

As far as I can tell from DP Edge's in my club, the construction details are almost identical.
