thanks guys.  yeah, 20 feet is a lot, and the spring mat does help... well, for confidence, i actually think that you get less power off a spring mat, but anyway, that's a diff debate.  as for the wall thing... i dont know, i just saw it, and thought that it might be fun to do, i was more messing around.  actually that most of what i did.  the craziest parts of the vid were actually just the huge cat at the top to top fountain part, and the rail to rail nearer the end of the vid.  so all the stuff you guys have been mentioning have suprised me i expected more comments on those other things, but still cool to get such positive feedback.  i preciate it.  sorry again bout the vid quality, if anyone wants ot take that time and make me a better vid, i wont stop em haha
