Road liner pads are an option, but again, I'd only want them if I were mainly working on concrete or asphalt. They are primarily designed as a more durable option for demolition and other hard use where you still need to track on good pavement. As noted, traction isn't very good, may even be the worst traction of the three (steel vs rubber vs roadliner). They are supposed to go on every pad, although I have seen guys run them on every other.
From your info it says your location is wnc, is that Western North Carolina? If so I'm assuming you're in the mountains? Are you crossing paved driveways frequently? What type of work will you be doing with the machine?
As for the rubber tracks, the most expensive ones may actually be your best value. I know that sounds crazy, but the OEM tracks (or an OEM brand, ie Bridgestone, etc) will outlast most aftermarket tracks by 2-3 times and be far less likely to get thrown off.
