You can tt as both characters my friend. The 4 man thing where you switch off is only when you have four tter's in a match. An example of what you can do look at Homicide on Anarchy. He uses both Homicide and Hernandez in his trashtalks regardless of if its a single match, tag match etc. Now for the 4 person look at either this week's tag team title match or the match at Lockdown is how that is done. That is usually done when you have two trash talkers (Or three in case of six man tag) on each side. That is when one team posts and then the other back and forth. I hope that helps clear things up for you, but feel free this week to post as both Barrett and Deebs.
