I’m confused when looking at this on a kicker. It looks exactly the same as a tantrum? Whats the difference?

Any tips on the edge and release? I find I can't get any pop or height off the water

I have been slowing the boat down to 18.5 mph can I still land it because I feel every time I do it I don't get all the way around ?

Is there a way I can practice this without a trampoline or while out wakeboarding?
