I have a 2000 Grand Touring 600 with a long track M10. It has Fox shocks. It is time to have them rebuilt. I saw a thread under Ski Doo where it was recommended 1) buy Ohlins 2) buy Ryde FX 3) have the seals replaced with an aftermarket that works better. How good a choice is replacing the seals? (obviously the cheapest) If this is a good route to go - what should I replace them with? What is the best route? I hear Ohlins are expensive. Is it worth it?
