I like the grouser bar style. I've had the Loegering pad style and they worked well too. Main thing is when you run them leave a little more slack than is recommended. I ran mine just tight enough that the tires wouldn't slip. You wear the links on the track more that way but it's better than wearing the axle bearings, drive chains and sprockets in my opinion. There are some cheap pad style tracks out there that break the pads pretty easily if you run over rocks. If you're looking at used, make sure you look at the grab bars on the bottom of the track that meet the tire and check the links and pins for excessive wear. I have a customer with a set of Prowler tracks (ebay) and he really likes them. They seem okay but look like they would be more brittle and easier to break than the grouser and I think the pins are a little lighter than Grouser and Loegering.
