Yeah, I run BMX pins in the winter and they're great, I can wear my sorel boots and not have to worry about yet another pair of special shoes for one thing. The platforms let me use my regular boots in the fall/spring rain without being over-insulated. Basically, I like the flexibility I have with platforms.
The pins are nice too, they're more comfortable on soft-soled shoes, 'cos in the spring/summer my winter bike can work for guests if they need a ride to a show or the bar or if I feel like riding it around town.
