Should i create a new xbox live account?

Ok I glitched one of my accounts for mw2 so i got al titles and all that. I want to sell it and I made a new account and the 1 month of live for free is about to expire and thinking if i should sell my 10th and just keep playing on that one. Im lvl 70 no prestige on the new account..what do you think? and YES I DONT CARE that i modded it. it's a game so dont wine to me that i did so.
