I think half chaps are wonderful! I think someone mentioned this, but make sure they are very snug and very tall when you start off. They will stretch out (esp the cheaper ones, and some of the expensive ones too!) and break down a bit, just like tall boots. If you want a really good fit I'd take a tape measure and measure the widest part of your calf and then the length from the back of your knee to the floor. Then look at size charts to see what would be the best for you. Tredsteps and ProChaps are my favorite brands. Mainly b/c their sizing is length x width instead of S M L so you get a more custom fit. They're both a little more expensive but fabulous quality.
