I use my own name as well.

That said, I don't think there's anything wrong with calling yourself TC3 - even if you're playing solo. The name is catchy, and if anyone asks what the 3 stands for - you can make something up, or just plug the fact that you're available as a trio.

I don't think its a good idea to keep changing names. You get a name and you stick with it -- or you have no name recognition...
