i have a pretty old trampoline and i don't get very much bounce out of it at all. when you jump the tarp almost hits the ground below you. i would like to use my tramp as a training tool this summer but because its so not bouncy i can't really throw many large tricks. is there any way to increase the bounce on the tramp? i heard crossing the springs works but i am skeptic if that would work. if i have to buy a new tarp and springs so be it. +K for good answers and please no hate.
