Edit: seems i got myself into a vintage A-profile trap, since that is what i'm talking about here;
the part about cherry profile caps bottoming out on top of the switch casing as opposed to asian/oem profile on the bottom
may still hold true though (further experiments ahead);
One interesting thing to note about cherry profile: while overall the keys are significantly lower than "Asian" profile, the modifier row is actually slightly taller. In particular it's more steep (the image is slightly down perspective, it's about 0.6mm difference in the middle of the tall end).![](http://i.imgur.com/Z0iUW.jpg)
For that reason i will probably use cherry profile with asian modifiers and a cherry spacebar (i hate my current spacebar).
Also i compared the stem lengths of the mod keys: the cherry is 3.8mm, the asian is 4.4mm
that's measured from stem end to strengthening fins;
This seemingly (preliminary testing only) changes the bottom out stop point:
Asian profile mod keys bottom out in the switch bottom, while cherry touch on the switch top.
That would also mean that o-rings on asian profile represent a switch from bottom to top contact.
