Word of advice mate
When you start on them remember that you are not on a trampoline
I know it is tempting to think that it will be the same but --
You will have a lot of weight strapped to your legs so things like flips will have to be re-learned
Also if you get it wrong on a tramp you can always sit down
Now you can do this on stilts
but it hurts
So go careful for your first few days until you get the ballance right
Not as much fun I know but better than breaking something
And don't forget pads for you and protection for your springs (if is possible to damage a spring badly when falling)
