Ishie:For current dives, I discovered that scoping out your subject in advance, and flipping to take the picture between your legs as you go by, often upside down, works quite well while avoiding breaking anything.
How about gliding sideways in the first place and simply turning so your feet are going first when you want a shot? I've found this will often give me a few added seconds needed to get the shot I want and I don't get dizzy It's also easier to stop or slow down and hold position when you can kick a bit...
