Good point PJ. I'm currently on a 2008 six carbon six with everything upgraded including the fork. The bike actually feels pretty good after a pro fitting. I guess I should also point out that I would like to stay under 3500.00 dollars on a new frameset.
I believe your Six is an '09. I don't think they were made in '08, but could be mistaken.
AFAIK, the geo for 2011 SL3 hasn't been published yet, but making the assumption that it won't change from 2010 and that you're going with standard geo (as opposed to team) the geo between the Six and SL3 in a 56cm is indistinguishable. I checked line by line and think you'll be hard pressed to tell a difference between the SL3 and your bike, assuming both are set up the same.
FWIW on the SL3 with team geo, standover drops by 1cm and HT length drops by 2cm's.
Lastly, you mention that you upgraded your fork. If it's only an upgrade in weight/ stiffness it won't matter, but if you changed the rake in the process, it changes trail (and in turn, handling) and that isn't reflected n the geo charts, so something to be aware of.
