I have worn out my Colngao Master, over 30,000kms, and a some rust has helped to finish the job. I am 6'2", and about 200lbs. I am a strong rider, Cat. 3, seldom race, enjoy hill climbs (self-punishment), long rides 100 miles, and maybe a time trial once or twice a year.

Is there any real difference between the two grades of Titanium. I am looking at the Vortex vs. Tuscany, and the Merlin 6.4 vs. 3-2.5. Price is not an issue, although I won't spend the extra if I don't need too, I will if a non-pro will notice a big difference in the two rides, if not, there is no sense in wasting money.
