I cant believe the high wear on the STS as well. I would never own one but have a buddy that has ran several 50s and 60sts, I love my walkers and plan on adding a third to the fleet this year. ANother thing is the ground conditions only allow so much speed, STS cant go any faster than a walker here, BUT I can add a pretty tricked out 9600 to my fleet for around 55000, try getting an STS for around that price that is not scrap iron. In our dry land I can go as fast as the sickle can cut. In the long run more money goes home in your pocket when running walkers over STS, and im sure its been proven time and time again.
