I find the 2-bolt seatposts quite easy to use and set up. John's description of how to best make it work corresponds very closely to mine. The sole thing that I would add is that I have a 10 mm wrench with a closed head with 12 indents (which doubles the chances of finding a perfect fit even if only tightening from behind between the rails.) Personally, I find it to be better than the purpose-built Campagnolo wrench. Using this wrench the Campagnolo design becomes simple, fast and permanent. I can't ask for anything more.
