Your question leads into my question.
I still have the factory track and it suits me just fine. The trails where I live take a beating so its almost always hardpack that I'm driving on.
I used the nylon backer plates instead of aluminum or steel for one reason, if the track gets hung up on say a pair of rocks or a log, with the nylon backers they would break allowing the stud to freely fall out or provide more leverage. With the aluminum, it would tear the stud out and leave a good size hole after-weakening the track further. Some guy told me this and it makes sense, just wondering what everybody elses opinion is.
If this is true, then it would be especially important with a track with high lugs since you would need an even longer stud or if you have a single ply track. The weight savings in their marketing is pretty miniscule. A few ounces here and there not enough to equal 1-2km/hr difference
