Weight isn't a big factor for me. I always used valve or hybrid amps then tried the class D stuff for a few years. I eventually went back to my bigger older amps because to me they just sound and work better for me. I don't consider them particularly heavy.
I used Hartke cabs for years , some heavy some not. I then used Vanderkley for a few years. Great well made etc cabs but I went back to Hartke because I prefer the way they sound to me. I don't care if they are technically better or worse than others , I use what works for me best.
I also spend a lot more time playing through my gear than carrying it so to me , weight isn't the main factor when choosing gear and I know a lot of other people who think the same.
