@FingerDub I understand no ill intent. A couple thoughts to ponder. First there are plenty of rock bands from the 70's that are pushing 70 years old that are playing some variety of vintage heavy metal. Heavy metal doesn't just belong to one age group.
Second, it would be interesting if you put up a curtain in front of your stage amp and DI'ed it through the FOH and monitors. First the "fridge" then a Class D with a couple Neo cabinets. Once the cab mixes with the rest of the band and throws out to the audience, it might have a different character than onstage. You might be surprised. For some people it isn't about having the biggest amp onstage, it's about using the best advanced technologies and achieving similar or superior results. On the flip side of that coin, if you enjoy your large gear, I wish for you all the happiness it gives you.
