It's nice to see the E-60 work out so well for you, Fran, but I have this gut feeling that you won't be keeping it too long.
I don't mean this in a negative way, but I believe it is too similar to the G70, and because it doesn't really have more than the latter, there is really nothing much to explore beyond what you've already achieved on the G70.
I think it will be just a passing fancy like the previous keyboards, and once the honeymoon of a "new" instrument has passed, you will sell it and try something else with new things to explore....nothing wrong with that.
In any case, it is cool that it will serve as a substitute for the G70 on certain gigs...definitely lighter and easier to manage and that's got to count for something.
All the best of luck with it.
Ian
