Not sure I agree with the 76 being only good for home, while gigging players would want a 61. One would have thought the other way round, to be frank, gigging keyboard players being more likely to have the chops to play some proper piano stuff, and the home hobbyist less so.

I doubt any home pianist is going to feel happy with less than 88 weighted, but the gigging player is rather more concerned about weight. And 88 choices for a full TOTL level arranger are non-existent, some kind of unwritten rule seems to dictate only MOTL capabilities for 88 note arrangers 🤬

But 76 arranger weights have plummeted to the point that they are barely a couple of pounds over the weight of a 61. And you’ve got to be driving a subcompact tiny car before a 76 is too big as long as you don’t buy an oversized case. In this day and age of SUV’s and pickup trucks the size of whales, who HASN’T got room for a 76?!

My BK-9, in a hard plastic case with wheels weighs 5lbs less than my G70 did alone! Maybe it’s time to acknowledge that progress has made some of the old arguments a bit moot?
