im like 160 lbs and 6'4, my friend has the oval one and i can bounce pretty high without touching the ground. the only thing i didnt like is the nets, i dont know if his was just put together wrong, but instead of holding you inside when you fall on the net, his falls right over and you roll onto the ground... but overall i like how smooth the bounce of his is compared to my normal spring tramp. and i could jump way higher on his.
