Which keys?
 

Which do you prefer? Organ or Piano? Each has their pro's and con's but for me im going to go with the Organ. I play piano, but the organ has the raw power to not need to be amped out to oblivion to be heard. Also its sustained notes create a unique obsticle for musicality making good orgnaists sort of nomads, their always moving, it strikes me.

The organ solo is a lost rock icon. How about you?

Depends on the type of music (obviously), but in most situations, I'd prefer the sound of an acoustic piano by a mile. I just like the sound a lot more. It also fits better with most of the music I listen to (mostly played with acoustic instruments), and in most of those situations it doesn't need to be amped to death.
