Here's another consideration. If you are getting the Ti model Serotta consider the Brooks Finesse as it is also Ti and is a nice light weight balance to the bike. The men's Team Pro (CroMo rails) made my bikes feel top-heavy.
The folks at Wallbike can walk you through the different uses for the saddles. You might also look at the TE for sale for saddles as well. I am reminded by my new Finesse that Brooks saddles tend to be a bit slippery when new. This will resolve with time, a little Proofhide and patience.
Happy riding,
