Seriously though I like the analogy. I guess my real issue is how optimal is the optimal choice? While in theory the taller and narrow 16s are the better choice in the real world is it a noticeable difference since the variation is relatively small (less than an inch in width)?
I went through the same process when buying a winter set for my 328iT. I was willing to go with 16s, but found that my preferred wheel was not in stock and ended up going with 17s.

Re tire sizes, you could actually thinking about further choices -- with narrower and wider tires available in both diameters. Given that narrower is better-- truthfully, though, I think the difference is not dramatic -- think about this:
16-inch: Narrower 205/55R-16 or wider 225/50R-16
17-inch: Narrower 205/50R-17 or wider 225/45R-17
and so in my case, I was willing to go wider for non-snow performance and ended up with a 225 tire.
