Well you asked for opinions...

I have had both, the Dragon and the Classic Flash (still have the flash), as other have stated there is no comparison if you want overall performance and durability. I sold the Dragon as I didn't need it along with the Flash.

I would recommend the Flash hands down, it is built like as strong as a battle ship but doesn't have the weight.

The dragon flew fine, but I made a decision to move it out and keep my trusty Flash...
As far as the comment on the snapping of the Ultra, I can not comment as I don't have that wing, I can tell you I set up all of my Jets with about 3 mm of crow in an effort to reduce the tendency to snap at very low landing speeds, I found that out with the JL T-45, talk about snapping....
