As to which combo, I'd ask are you looking for warm, round, mellower tone, or a somewhat more aggressive, modern tone? I have the 15, and it is quite articulate, but not overly warm. The 210 supposedly is the slightly more aggressive and "in your face" voiced of the 2, but I have not personally heard one. I can make the 15 sound more than aggressive enough for my taste. I am very glad I chose the 15. YMMV. How either would sound with an (8 ohm) extension other than a Contour cab is a crap shoot (maybe great, maybe not so great). Only one way to find out! Heck this thing is darn loud by itself; you may find you don't need an extension as often as you think! They are GREAT value for the $$. Good luck! Let us know which one you get!
