My first year owning one - I'd have to say I was a bit worried at first when I saw it bending and flexing when the kids really got some waves going - but it seems to be well enough designed to withstand it all. Perhaps those who have owned one for many years can inject a bit more confidence - but what you're describing should not be a problem.
Ours was 18 foot 26000ltr round ultraframe pool 52 inches deep and that thing was amazing. it was full and standing up beautifully even after being up for 11 months strait summer to summer, with 2adults and 2 pre teens using it and jumping in, trying to make whirl pools, etc etc. Highly recommend round ones as being very sturdy and exceeding all expectations
