Primarily, band use. I play all verses and solo on the second. When playing back up, I will always be able to support and cut through when soloing. There are always 6-15 band members with all the acoustic instruments, but not organ. I will see as I go along about other uses.

As an aside, It will be refreshing to bounce in with a 15 lb keyboard instead of trucking in a big one, all though that has never been a determining factor.
