I'm in the same boat as almost everyone else. I have 5950's that are all the "same" size but vary quite a lot. I have a few that are unwearable because they are small, large ones, and ones that are perfect. One trick I've found for helping the fit (and can even be used to eliminate high crowns) is by heating up the inside with a blow dryer on high until it's almost too hot to touch and then putting it on while cupping it with your hands to your head, repeating the process as much as necessary. Basically you are just melting the polyester just enough to conform perfectly to your head. You just have to be careful because it can warp your hat if you get it too hot. It can be really uncomfortable to put a hot hat on your head but it goes away pretty quick and I find myself doing it with every cap I own now. Took an almost unwearable Cleveland Indians 5950 into one of my favorite hats.
