Without any heat usage, it is pretty much the best option you may have, and if you get a CH on 5C frame trap or 5B, you can link in into a 2C 2D 66 2C 214A~C~B etc etc, but of course the best corner carry combo is off a grab, that's hard to beat (meterless), with meter it would be like 2A 5CC 214A~CCCC RC 66 into whatever but never use 2A 5B 5CC 214A~CCCC the 5B ruins it all and makes you unable to link a 2D after the RC (same for a few other combos).
