Yes! reverts at landing. That's actually something that can add more style to the riding... and I'm all about style! :)
I'm still not sure what button to use. The B button seems to be the way to go but it could cause problems if you want to reverts while landing on a narrow ledge, like the grind detection might kicks in. I need to test it.
Another way is to revert with Triggers. It will be more advance feature since you will need to choose the proper trigger (nose or tail) to revert.
