Dennis, I am the MASTER at half air half water flips.
Maybe I could call that a 50/50 flip?
Hey Ed, there is a surf company that makes a snap in system: o'fish'l. Inland Surfer used to use it in years gone by. http://www.ofishl.com/
They have a tag line about metal screws fin systems: "Don't get Screwed"
Tell me something, if in a competition, I have 2 falls, I can use them (ok not me, but let's say someone with talent, like...oh maybe James?
) by say having is routine be slaysh, air, 3 and then a superman. They start him again and he does slasyh, air, air, 180, 360 then at the turn around a front flip.
I think there are tricks that can be performed that are halfpipe inspired or mx inspired if we just say - huh, I'm going to attempt that.
