wow ! no fear there !
but as jason said, pads are a great idea , as if you are injured you cant bock ! so would be a shame for the sake of some protection.
even if you can do the flips , things can go wrong, so i always use my wrist guards !
As for help on the fronts , it can help on a trampoline to get the right technique without to much pain , as you seem to be dropping your shoulder causing you to not go over straight .
but love the enthusiasm !!!!
