I've been amazed at the gigs I've been able to cover with just a Hathor 1203 and a Aguilar TH350. It helps that both my guitar players are now going direct through Line 6 HD500s. The Hathor is so small and light, I smile every time I load my bass rig in or out! My second choice when I was cab shopping was the Fearless F112. All of the current "super 12s" seem to cover the bottom end of "modern sounding" pretty well. Your description of your tone as "somewhat modern" makes me wonder if a F112 may be more modern that you need up top. I'm sure you can EQ it to give you your sound, but why pay for the sizzle if you're not going to use it. Having the ability to set an F112 in an floor monitor position is a very cool feature if you need such a thing.
I didn't have a chance to try before buying, but I knew based on classifieds activity that I'd be able to flip a Hathor for pretty close to what I paid for it if I didn't like it, so it was a low risk decision. Only question now is should I get another one to cover larger outdoor stages I do a couple of times a year and sell my 2 big cabs. Bottom line, as I'm sure you're getting by now, is that there are lots of great choices and different flavors of awesome. Good luck with your gear quest.
