My poll includes some examples but they're not etched in stone. Feel free to elaborate on your particular preference. Note: you can vote on more than one option. I think I like Vic's and Will's approach. they vary their steady gigs with good side projects that keep the main gig interesting. Of course, Vic and Will are pretty popular guys overall, so if I didn't have their marketability, I'd try to do the sideman/studio thing.
