Looks like you should keep your TK11. I didn't see anything in those beamshots that I would call an UPGRADE. In fact, it looks to me like the TK11 tied or even beat the best of them (except for the Spear, that seemed to be the winner). Oh and that C2 R2 and incan both kicked butt as well but I'm not seeing any point in giving up your TK11 exept maybe for the Spear.
