Does ex hat spin have any use?
Also what is the max damage combo you can do from a raw ex spin? Corner + midscreen?
I said it somewhere else, but Ex hat spin gives you on so much frame advantage that you can nap, go to France, meet your future spouse, get married, have kids, send them to college, grow old in the alps, and come back and still be at an advantage. So really ending any string in ex hat will guarantee your opponent has to block your next move.
And for any combo involving raw ex spin, you should be able to get 30-35+ midscreen and corner. check out ETC McFly's combo video
