Thanks for the feedback! I rode it like this for my commute and hated the saddle height. I've since cranked it back up to 81cm. I've also had it set to 82cm and I feel like that is my most powerful position, but I also felt like I was sitting on the nose of the saddle and was getting some discomfort, which I assumed meant it was too high. I didn't play with the fore-aft position at that height and I probably should, since 3cm of saddle height probably has an effect on the setback.
