Well, I have come to realize I am very bad at that!
When I look at my show roster spreadsheets, my sport/warmblood category is nearly empty, my draft/pony category is pretty much nonexistent, and my stock horse category is actually entirely empty as far as traditional models go. To be fair, I've never been into stock horses much, and there aren't many stock molds out there I like. For some reason a good roman nose and a nice crest are what draw me in, big hips aren't really my thing I guess!
I really hope to "diversify" my show string before my spring shows. I want to get a few Lady Phases to bring some life to my stock horse category, because I actually do like that mold and she's pretty reliable in the ring. I'm thinking the chestnut treasure hunt horse for a QH, the appaloosa Breyerfest SR Sprinkles, and perhaps Treasured Moves for a paint. As for drafts and ponies... well, I've never been a fan of ponies and I love drafts but don't like any of the molds outside of Othello and Shannondell, both of which are very popular and hard to get without paying a pretty penny. Maybe I'll figure something out eventually!
