Well that definitely should not be contributing to a harsh ride. I'd say you've got some air in the system, bum fluid or some other problem keeping it from performing right. With the age and mileage, I doubt your globes are shot.They are a load C. Been running 33 psi, but with the drop in temp this weekend I got in and they were all showing 30.
If you want to schlep up to Arvada, you're welcome to test drive mine for a comparison. Mine has 160k miles and is nowhere near peak condition, but still rides pretty nice and I can feel the handling sharpen up when I put it in sport. I pretty much never use comfort.
