Diki... Most of my music is SMF.  I realize the advantage of 76 keys, but I can manage with 61.  I've run my SMFs thru a SC88 lately, but have successfully used the G70 and the 3k as sound sources while still playing along.  I usually use the piano or organ modes as a full board while the SMFs play.
There are so many trade-offs when choosing a keyboard that focusing on just one feature is not fair for comparison.  As I said, I think Roland has it hands down when it comes to styling and keyboard, but Yamaha has equal fidelity with much less weight.
If I sell the G70, another 76-note board may well replace it (maybe something RED  

)
