I'm looking for a used carbon road bike and have narrowed it down to two bikes. I previously had an Orbea Orca which I loved. So I would appreciate any feedback on these two bikes.

First, 2008 Ridley Damocles with Ultegra SL 6600 group. Wheelset is Spinergy Stealth FCC. The bike has barely been ridden and has only 200 miles on it (wheels 2000 miles). This bike retailed for about $5k.

Second, 2009 Felt F3SL (stock bike) with SRAM Red group (mostly), SRAM Rival brakes, and SRAM S900 crank. Wheelset is Mavic Ksyrium Elite. This bike retailed for $3700.

Both are around the same $2k price range. I appreciate any details on your experiences with either of these bikes. Both have very stiff frames which is what I am looking for.
