I have a Felt F3 and a Fuji SST. I have not ride the Grand Fondo, but the Felt wins hand down on ride quality. I know the SST is a much stiffer bike than the F3. But I have a good amount of time on the Altamire and the Felt just rode better.
The Fuji is a good bike but will need some upgrades. The wheels, like stated above, most and of the Oval branded parts.
