Grab isn't really mix up unless you have a good overhead to use, that's why Tager players used to complain about having a mid/low game. It is an option, no doubt though.
On a semi related note, I think that players aren't utilizing his drill oki sufficiently. Once you set it and they block, that leaves plenty of room for additional pressure, especially lvl 3 drill.
When the fuck is this game coming out...
