I’m gonna counter the transition fear by saying it helps make a board slide to fakie/lip slide/fakie hang up slide about 10 times farther with no chance of sticking.
Also on disasters, if you are lazy and lean one way or another it makes it tricky but it teaches you to properly pop the trick and stay over your board. If you push your board up there and have a tendency to lean forward on back d’s you will have to spend some time re learning them.
Also smith grinds are much easier, yes it’s a cheat code but I’ll take it.
