I'm getting to the point where weight is more of a factor than it used to be, but 20 lbs for a solid 76 note arranger hasn't yet become an issue! I don't think it ever will...

I've tried so many times to play piano parts on a 61, and I always found myself whacking the end stops at either end (painful!) or having to transpose a split's lower part down an octave and have a hole in the middle of the keyboard (only painful to the ears!) to compensate.

Thank God the BK9 is so light! We both know what a tank that G70 was! 😱🤣
