Does anybody have any experience with these over the tire rubber tracks. AS far as how well they hold up to, will they get approximately 1,000 to 1,500 like a track on a CTL. Do they get as good of traction as a OTT steel track. Currently I have a set of Loegring steel tracks on my Bobcat 773G and can not justify the cost of a CTL. I like the performance I get from the steel tracks, but hate when you get a little 2-4 hr job that you can't run the steel tracks and have to take off or mess with putting plywood sheets down to run on. I see some solideal trackmaster brand for $1600 and then the other day I saw some brand for like $5,000 whats the difference. Havent' ever seen anybody in my area with these and was wondering what you guys know about them.
