My MkIV narrow combo is pretty weighty, which is why I always move it around in a roadcase, so I only need to lift it in and out of the truck. My Subways are all easy to move. If the Subway Rocket had a switchable effects loop, I'd probably use it all the time. I always run my MkIV in Class A triode mode, often on the Tweed setting, and the master volume is never above 5.
The other guitarist in my band finally replaced his Laney with a Studio 22, and it covers all the bases and isn't a back killer. I didn't realise until I saw his that the two channels have no shared controls, and there's no pull features. It's the Mesa for folks who like to keep it simple, and sounds great. Soundguys are always happy when they see our combos.
My rule of thumb for halfstacks is, if you're the guy moving and setting up your gear at the gig, a halfstack is too big for that room.
