I bought myself a second TNT Strong. My old one now has got some holes in it:
I've flown both today. The grey one flies like the old Strong, but it is a bit quicker in the tricks (more like my other TNT's, so that's good).
The Vented flies pretty good. Straight lines and corners no problem. Needs some adjustment at twopointlandings.
Tricks are all there, like Jacobsladder, Tazmachines, Multislots, Yoyo-related stuff, CrazyCopters. BUT: the kite tricks a lot slower now, espacially in Yoyo-tricks and RollingCascades. Maybe it needs a bit more weight, I'll try next time.
