Which Box Shift is actually best for ACAAN=?

[Emil129r]

Hello out there.

I have for a long time tried to find the perfect box shift for a ACAAN.

I have nearly only heard good things about Flip Shift by John Born.

But a friend of mine, has also told me, that Asi Wind should have a really good box shift?

Which one will you prefer, and which one is cleaner and best?

Best regards
-Emil

I like the Asi Wind version but I haven't learned the John Born version so I can't compare them
