The backspin itself is what slows the bb down. It's not necessarily the contact patch.
If you want to create spin quickly, I doubt there's a more efficient way than a patch. If you want to create the same amount of spin over time, then you should be looking at a LRB. Essentially it's a bent barrel in which the curve forces the bb down a path that will generate backspin.
