Depends on if you're going for more of a first coming Brock moveset or a current one. I use the Brock Lock as one of his finishers because I prefer an '02 moveset – setting it up that way also allows you to give Brock two standing finishers.
Why pick only one though? you could always make something of a hybrid moveset and give him the Kimura as a groggy, chain or punch reversal submission. --- WWE gamers are far and away the WORST community of cheats, simpletons and detestable filth in all of online gaming. The above statement is FACT.
Actually given how often he went for it against Triple H, I would say having Kimura as his standing BPS moves in all situations would make sense. --- ICEman Morgs' Ignore list: Making GameFAQs a better place. GT: Morgneto
