How are Sugino Mighty NJS seatposts? Or Dura Ace NJS seatposts for that matter? I'd like to get an NJS seatpost for my NJS bike (and no, it's not a full NJS build but right now it has an ultra-cheap Pyramid post on it that I told myself I'd switch out when I had more money). I don't really want to go for the Nitto Jaguar though, as it's an extra $50 compared to the aforementioned other two.
