Not myself... but a buddy has the v2 and says its WAAAAAY better than the v1... which was a miss.
Way better is not saying a lot, anyway.
After one flight of the Roger2 I found it to be exceedingly stable in the air, powerful, canopy does not collapse when pumping- turns a bit slower than the D-wing.
More to follow
I rode the 4m for the first time 2 days ago. Bar is comfy with the "J" end, canopy is very stable and provides a competitive low end. Steering is quick but not twitchy, and stowing is good too. Nice color coded lines too. I've not flown the first gen of the Roger, but I'd be happy with this V2. I did find the high end stability quite good, but it was pulling so hard that a harness felt like a must. I didn't have time to use the knotted depower system, so that may play a big role in getting the high end pull sorted. I flew the 3m on the beach and it had slightly shorter lines and also felt great to fly.
