Trailering cover for GT 700?

I'm looking into buying a trailering cover for my 2002 Ski-doo Grand Touring 700 Sport. The one I am interested in is the Classic Deluxe Cover from Classic Accessories.

I'm a little confused on what size to get, most covers for touring sleds are X-large, but according to their chart I would get a large. My sled length is 119.6". Anyone that has a GT that has bought a cover, would you tell me what size cover you have?

Thanks,
Dave
