I recently became a Helix convert, sort of by necessity. I'd been looking at the hardware units as I've had access to the native plugin for my studio for a while now. Took the plunge and have played a couple of shows already with it. I also recently had hand surgery on my right hand and cannot lift more than 5 pounds. My regular amp rig is similar to yours (6 watt VHT tube head, 112 cab--each in their own road cases, a medium sized pedal board, and a case for carrying cables and other accessories, plus 2 guitars in hard cases). Although the rig itself is "small", it's still quite heavy and unwieldy for me right now. First gig with the Helix: showed up, plugged the board into power, plugged guitar cable into Helix, put my 2 guitars on a double guitar stand and I was DONE. It took MAYBE 5 minutes and I could carry it all with one hand, however slow that would be. I thought I'd miss having an amp behind me. I don't. Even without in ear monitors, which I use regularly, I get plenty of what I need from provided floor wedges. Playing smaller clubs or pubs might be an issue, monitoring-wise, but so far I haven't had a problem. My first show with it was a large outdoor stage with a huge system. It sounded great. The next show was in a smaller, indoor club. It sounded great there, too. And exactly the same as the first show. A big annoyance for me is power variations in different venues creating tone anomalies, especially with pedals. Doesn't happen with Helix. Anyway, all this to say, if you don't wanna lug around an amp forever, the LT is probably your better option as you'll be able to phase out the amp in the future. With the HX, you're stuck with the amp. I hope this helps you.
