Well, you have your "doable" G70, so I'm glad you've got what you need.

Weighted keys do not restrict my arranger play...remember, I play/demo plenty of CVPs and as well as PSR and Tyros...plus I play piano a few hours just about every day.

The only sound that might not benefit from weighted action would be organ, and ONLY if you plan on doing smears and slides as on a waterfall keybed...even the unweighted/semi-weighted keys on MOST arranger keyboards don't work well for slides/smears because of their shape...I know you're going to say the G70's keys work well, but they are unique to that instrument.

For any other sound...guitar, sax, strings, whatever, weighted is fine, because you get used to the action, and your hands and fingers get stronger. It's no different playing fast piano licks from fast Sax licks if it always feels the same and you're used to it.

Regarding the chance I might have to play one piano tune, I plan my gigs very well...if I'm using auto accompaniment on a gig, I never get asked to do solo piano...it's not expected...I always know beforehand if I'll need my piano.

So don't knock weighted so easily...Yamaha sells a lot of CVP and I'm sure Roland does equally well with the KR-series...I'm sure their users don't use only the piano sound.

Again, it's what fits your needs and/or preferences..
