I got the poverty post. The whole set up with the post cut (about 20mm cut off) weights in at 13.1 oz
i shaved off 28 oz. from my old set up

The seat is super comfy but, the quality compared to my primo is way less. Only time will tell if this seat will handle the abuse.
One big down side is that there is no for and aft ajustment so it is where it is.

I looked at the posts that have the wedge built in and came to the conclusion that they are infact very heavy for there size. if you where to cut down any of the other posts and use a 0.8 oz seat post clamp the whole set up would be less then the one with the built in wedge. Not on;y that but i know for a fact that that wedge design is prone to jaming in place and wobbling at the top, causeing a creeking sound.
