Anybody have a vid or suggestion for fingertricking OLL'S 9, 10, 36, and 37 they are the fish shaped ones.
 
Does anyone have a center-safe J-perm? I am looking for a Jb perm that doesn't affect the centers. Thank you in advance.
 
I've been looking at some sites to get cubes from...is the china magic cube site good? because their stuff is really cheap.......

I'm not quite sure what you mean but I feel like the standered is R U R' F' R U R' U' R' F R2 U' R' U' I know the centers don't move at all with that one.
 
How? without double layer or slice turns whatever the center is on top will not change, less i'm misinturpreting the meaning of "move".

I interpreted it as affecting the centre, period. Meaning, no switching, no twisting. As in yours, if you add a U' at the end (so it's parity), it twists the centre in place. That being said, I don't know if he's looking for a J-perm from parity.

edit:
I don't know what you mean. Care to explain?

I just need a Jb perm, that when you perform, that centers are orientated the same way, as before you performed it.

I'm not 100% sure if I'm right, but a J-perm is parity because you're swapping 2 edges and 2 corners, and cannot be solved with a commutator (unless you add in AUF; closest I can get is F2[r2, D' L2 D]), and you have to twist a centre in place in order to solve it, as far as I know.
Why do you need one anyway? Trying to solve a supercube?
