I'm surprised that 700x32 tires aren't providing a comfortable ride. Can't see any reason why a CF fork wouldn't help. If it doesn't, then it's time to start thinking about a new bike. How about a nice Surly Cross Check, or better yet, a Surly Long Haul Trucker with 26 inch wheels? If a steel touring bike with fat 26 inch tires and a long wheelbase isn't comfortable enough for you, then maybe it's time for a recumbent trike?

I'm definitely going to ride a recumbent trike when I get old. With a fairing and a big orange flag. Gonna grow a beard and a gut, too.
