People are saying CM Punk needs to lose the G.T.S., I personally think he should stick with it. It's a move that gets him highly over with the crowd. Yeah, KENTA may be the innovator of the move, but when KENTA does the move, it looks horrible, mainly because his opponents oversell that move so much. Punk's opponents sell it perfectly. They don't go and flip over 2 times, they sell it like it should be sold. The Anaconda Vise was a great finisher as well, as it's different than other submission holds that WWE fans have seen, it's no Boston Crab variation, like the Walls of Jericho or Sharpshooter, it's a original move, that I believe no North American wrestler has used as a finisher. Another good thing about the Vise is that it can come out of nowhere, so it's a fast finisher to perform, so it's easy to pick up a win. Also, to everybody saying CM Punk was told to use that move, he wasn't. He chose to use that move, as a tribute to KENTA.
Also, MVP's Playmaker is a good finisher, MVP performs it very well, and he does make it look painful. If he is to change his finisher, he should use that Player's Boot, it's a very nice move, and the impact on the move is very brutal.
Now, for a superstar that needs to get a brand new finisher, it has got to be Bobby Lashley. Get rid of the Running Front Powerslam, you are not frickin' Davey Boy Smith. Get rid of the Spear as well, the Spear is used by too many wrestlers these days. Edge does it best, so leave it to Edge. Lashley should get a more powerful finisher. In my opinion, he should use the Dominator again, because he does that well, and makes the impact brutal. Or he should use a TKO or the F-5. Both have strong impacts, and inflict tons of damage. They both suit him as a powerhouse styled wrestler, and he can scoop his opponents up into the Fireman's Carry for the setup's out of nowhere.
A final superstar who needs a all brand new finisher is Rey Mysterio. The Tiger Feint Kick that he calls the 619 is just a horrible move, it's extremely weak looking, and takes a big setup to do. He even has to add a Springboard Leg Drop or Splash to add extra damage to even pin his opponent successfully. Rey should revert to using his classic Hurricanrana from his ECW and WCW days. He pulled them off fantastically. If not the Hurricanrana, he should use a Moonsault, or Moonsault Leg Drop. It would suit him well for his size, and athletic ability. He can easily perform them, and they would be more over with the crowd than a weak looking Feint Kick.
