I use Hartke cabs with mine. I have two cabs... a VX 410 and an XL 210. The 210 is great for small gigs. The 410 is for something bigger. I can throw them together get a nice sound for large rooms. I don't play HUGE gigs, but if I did I would just use a 410 as a monitor and go direct out of the amps DI to the FOH.
I used to have a VX115, but I sold it. I never used it.
If you can afford the extra cash for the tour 700, I'd say do it. The only difference between the two amps is power. I don't think I need the extra power of the 700, but, hell, having more power on tap is good thing.
I also recommend the Peavey cabs. They are great cabs.
