Noticed a few big players(bepoop\pungay) are doing the slower strat for emergency exit when this one is easier and saves .5(.1 more if you don't dust the ledge)
This one is for SSL Reds, I speedkick before long jumping and then insta-dive instead of A->B jump diving. I find that it puts me higher up on the hill, giving me more speed and improving consistency of getting the speed slidekick.
To add to this, you can also C-Left twice instead of once in the beginning to help your angle as I find kicking before long jumping kind of screws it up with these camera's.
Towards the end of SSL reds, when triple jumping off of the 3rd pillar, you can use aris' swag sideflip. From what I can tell it doesn't really save anything, but it's a lot easier than it looks.
When doing the alternate WDW Secrets, if you wall-kick on the right side of this wall and then forward sideflip up to the box, you can avoid the shockball 100% of the time, it is also just as fast and\or faster.
