Not having a micro head really isn't a big deal, I was so happy to have a pair of 210 cabs (for close to 10 years now) that weighed under 40lbs and the V4B is basically the same footprint and weight. Until they can make an 810 that fits in my gig bag pocket the V4B really isn't inconvenient.
Agreed 100%! You gotta lug something, and the minor hassle factor this has over the micro stuff is, IMHO, far outweighed by onstage efficiency, convenience and tone.
What are you using to hang your bass on your amp.
I'm using one of these String Swing things: Clip-On Guitar Hanger for Suitcase Handle - String Swing (R) - Guitar Hangers & Instrument Displays
But I went to the local hardware store and got some self-adhesive felt and stuck that on the inside right-angle-part of it, and taped some plastic tubing around the hook that goes under the handle on the amp to keep it from potentially marring the surface the cab (don't know if it would, but I don't wanna find out the hard way!). That P bass only weighs 7.8 pounds so it's not really even stressing it.
