I flew a V1 WH Edge with a ZDZ 60 that madiened at 19 3/4 lbs, she flew decently, however was much more capable at 17 lbs. I also flew the WH Ultimate at 19 1/2lbs, and she as well flew much better at 17 1/2 lbs.
Now I have the V2 Extra at 16 1/4 lbs and it is again different, better yep, easier to land yep, but it is a different bird.
