My Lynskey Sportive suffered a cracked chainstay earlier this season, and I was riding a very nice borrowed Cannondale Synapse while it was being repaired. The first time I got back on the Lynskey, I was shocked at how much I had missed it. I would strip the 6800 parts and dump the Madone if it isn't doing it for you. Not sure I would go with a tank like the Gunnar, considering how nice the Ti rides. Maybe get an different Ti frame to build up with the 6800 parts? A Helix or R series?
