Champ,
You seemed to have less problems with yours than Marty had with his, and you seemed to launch it better too....and you're close to twice his weight. He kind of gave up on his I think...it ran well but he seemed to have some problems getting the most out of it.
Fritz used to go like hell on his and he's huge. In fact Fritz used to beat Marty....which seemed kind of strange...being that he's easily 100 lbs heavier.
