4x4 pieces from a cherry log?

I have a good shot at getting about half of a cherry log that's roughly 16 inches by 16 feet, give or take. My friend hasn't measured it but he's got a good eye. If it works out I'll be splitting it with a guy who has a bandsaw mill.
For some reason I've been lucky with cherry recently and I've got enough for a couple projects. But I want to make some cabriole legs and can't find any cherry that's 3 1/2 square and three or four feet long. So I'd like to see how much I can get from this.
The log's not painted at the ends and it's been there about a year. I'll paint it when I get to it and the guy with the saw, so far, will cut it the way I want as long as I help him get his share cut up too. No problem.
Except maybe I shouldn't do it. Or maybe I'll have him cut it up all wrong. As far as I can figure out, I want these chunks from about midway from middle, not too close to the sapwood but not too close to the center either. It'll dry in the garage/woodshop, probably.
Should I even try this? Anything else I should watch out for? I've got a copy of "Understanding Wood" and I'm reading it again, but I usually miss the stuff I should have seen, especially first time.
Thanks for any advice you can give me.
