OH friendly please
H perm avoidance is easy. I assume you know what the case looks like (centers on R and L solved).
When you get it, instead of doing whichever trigger, do a y2 and do the trigger. Then y2 and the inverse of that trigger.
For nasty Pi cases, all I can say is just turn fast. I don't know the advanced cases for them yet.
Thanks!
