That looks a great rig, with all the virtues present - sound, reliability, looks and portability. Gonna have to get me one o' them 310's, though I am still interested in the 210 and I can't have both.
As to the other matters in your post, I'm probably not even the best bass player in most of the bands I play in, never mind the entire region, but thanks anyhow. I'm good at finding gear that works for me, though...
Btw, those heads fit exactly into a bog standard camera/ equipment/ tool case with room for a mains and speaker cable.
How's the wireless set-up working for you? Saves a bit of onstage tangle and I'm guessing no effect on tone ?
