Fran, I know you didn't buy the KMA to replace your main axe.
I wouldn't either.
Most professionals grow along with their main axe, and get the most out of it, and it becomes a part of your playing style...you sorta grow together.
The Tyros4 means the same to me as your G-70 does to you...we're both on the same page with this.
I know the KMA was just a fun thing for you...but some have taken it very seriously, and then mysteriously, made a 180 degree change and dismissed it.
I don't think either of us does that.
Ian
