Vacuum Tube - 6L6WGC, Tube Amp Doctor

I'm an amateur and may be over thinking this. I have a single-ended Champ 12 for which you recommend this tube, and I play a baritone guitar. I'm replacing the stock speaker in my amp with an Eminence Swamp Thang, which I understand is focused more towards bass, but is neutral according to what I've read elsewhere. Which of the TAD 6L6GC's (or other tube) would you suggest for my application?

The Electro-Harmonix 6L6 has a nice tight response. Most low powered Fender amps have the tendency to get fuzzy in the low end. With that in mind, a tube swap will not change the inherent design of the circuit but may help a bit.
