I'll be fickle about this, Trey & Matt are Amazing as their characters, but a friend of mine wishes that 50% of the voice acting was done by More Voice Actors. I mean April Stewart, Eilza Schnider, Mona Marshall & the Late Mary Kay Bergman are Actual Voice Actors, but What I mean is if Trey & Matt's Roles were done by the actual VA instead. In a Diffrent World, This is what I would Choose & yes, they can still use the Pitch Shifting for the Boys. Grey Griffin - Stan Marsh, Bradley Biggle, Ms. Choksondik Tara Strong - Kyle Broflovski, Scott Malkinson, Kevin Stoley Jennifer Hale - Eric Cartman, Kenny McKormick, Pip Pirrup Dee Bradley Baker - Butters Stotch, Timmy Burch, Gerald Broflovski, Jimmy Vulmer, Big Gay Al Nolan North - Clyde Donovan, PC Principal, Phillip, Stephen Stotch, Dr. Alphonse Mephesto, Jesus, Saddam Hussein, DogPoo Petuski Steven Blum - Craig Tucker, Stuart McCormick, Ned Gerblanski, Tuong Lu Kim Jeff Bennett - Tweek Tweak, Randy Marsh, Officer Barbrady, Terrance, Dr. Gouache, Father Maxi, Grandpa Marvin Marsh Jim Cummings - Mr. Garrison, Mr. Mackey, Jimbo Kern, Satan, Jason Sean Schemmell - Sergeant Harrison Yates Charlie Adler - Mr. Adler, Bill Allen, Fosse McDonald That's my 2 cents for now. I can't help it but it would be hilarious if it did happen.
