I really don't know what I would do.
I just remember gixxer6 commenting on here about installing a 1" track on an Invader and how much it improved the traction.
I look at my Kawi's, Sidewinder, and Blizzard and the track lugs are only about 1/2"....I can believe a 1" track would be amazing.
I would love to try one of the new "Ice Attack" style tracks that have something like 244 carbide screws embedded in the track with a 1" lug. In a perfect world, that is what I would want to put on an Invader.
But, they are about 550 bucks!
Really, my '97 SkiDoo MXZ is the one out of all of my current sleds, that will need a new track before too long, so I may try one of those tracks on it.
Since I'm cheap, I would probably run your current track.
I can tell you I got my '83 Yamaha Vmax in 1989. It had 96 of the old style studs, with the T nuts, in the track. They were pretty worn out. So, I removed all of the studs. I was worried that the open holes in the track might start to tear out, but after several thousand miles, the track is still holding together. But, it isn't the greatest solution.....one branch or something sticking up through the snow could snag one of those open holes and it would start to tear.
