Went out for my first ride on my freshly serviced shock yesterday, I was pretty amazed by the difference in ride quality and handling, I guess you don't notice the degradation in performance as it happens so slowly over time. I only thought about getting the shock serviced as I felt my recently serviced and resprung forks were outperforming the shock which is ~4 years old. Well worth doing if you have a shock that's a few years old or has seen some big miles (Nitron recommend servicing at 12-18,000m).
