Ease in adjustability is nice, but how often do you really adjust your seatpost?
If you buy a Thomson, get a used one. If I hadn't found a $30 Thomson on CL, I would be running another Kalloy of some sort on my Cross Check right now.
Thomson setback = about the same as any other seatpost. Don't buy a Thomson setback thinking that you're gonna gain any cockpit space, because you won't. The straight one is great for moving you a little bit forward, though.
Don't buy a Miche Supertype if you're gonna run a Brooks. It makes you look like an idiot.
