I've used them on a few bikes--only 1st gen I believe. The lightweight was definitely a big part of the appeal of these posts BITD, but I also like the relatively sleek and unusual design. They polish up nicely, too. I'm currently using one on my Merlin with a Flite saddle, and I weigh not much less than you. That said, I also had an AC on my race bike back in the 80s, and that one did eventually needed to be replaced due to loosening and, as I vaguely recall, some issue with the tension bolt.

Is this a show your American Classic seatpost thread?
