for exsample
When I get a Sune OLL case I do a Sune in 4 of 6 cases, I do a niklas 1st when it solves all corners and 2nd to prevent on of the 5 long diagonal PLLs (E,N,V,Y).
This way I can restrict the additional recognition to just looking at two stickers, wich is near to nothing. (regular coll recognition needs 3 -4 stickers)
The other Sune-COLLs I know I don't use in fridrich solves.
I don't know if someone else is using this for all OLL cases.
