The biggest thing to remember when mixing and matching speakers is to try to get similar efficiencies. If you have one speaker at 93db and one at 101db, the 8db difference will mean that you really only hear the more efficient one unless you have your ear to the other!
I have lots of different speakers (Celestion, Eminence, Goodmans, Tone Tubby, Scumback, Jenson (originals), JBL and others). Depending on what you are going for, I like the Scumbacks, Eminence Tone Spotter, Eminence Blue Tick Hound, Celestion Sidewinder (possibly my favourite), and JBL's in Fender Blackface amps.
I know this wasn't much help in which speaker to go for, but you like the one speaker I don't - the V30 - I have used them but never get on with their tone. I would tell you to look for Sidewinders if you can find them and then you will never want anything else!
