If I had a crew, you BET I'd still be using a B3, Rhodes, real piano etc.!
But what we are talking about is the difference in weight between arrangers, no more than twenty pounds TOPS. S910 about 27 lbs., G70 45 lbs.. Unless infirmity is the reason, we are talking about decisions that have fairly big consequences (S910 is a great arranger, but the T3 sounds considerably better) for the saving of a mere 20 lbs...
It's obvious that that decision is a lot more practical when you are comparing a 28 lbs. arranger with over a thousand pounds of vintage gear

but most of us COULD lug around a few more pounds of weight if we considered that the improvement was worth it. What surprises me is the admission that the improvement ISN'T worth it for some of us, to be honest!
