Mclaren is where it is at on tracks. Personally, I would only use over the tire tracks as a last resort. If you are looking to run tracks full time, you should consider trading in your machine for something set up for them, or putting on a full track conversion. Over the tire's aren't bad for ocational use, but they are a real pain to install, and only give you partial benifits compared to a true track machine. If you do go to a real track machine, take a good look at Takeuchi, by far the best track machine on the market for rough terrain use IMO.
