The 2plus tracks are made by www.tracksplus.com and are available cheaper under the latter name.
I have sold the tracksplus for the past 3 years and have never had anyone with a failure. Life is in the 1500 to 1800 hour range. They are the lightest weight (non chain sidelink) track. So they offer better floation on soft ground because your overall weight is lower. Also tthey have a large pad to better support the machine. Are rockwell 48 to 52 hardness makes them wear well
The pro tracks are a dual bar style shoe. I believe they are heavier and appear to have many satisfied customers too. Though I have never used them or seen them in person. The pro tracks are several hundred dollars more, I have never heard a quote on life span.
