I love my Badlands, very aggressive tread, very slow wear to them. I run mainly in mid length grass and loose dirt and get excellent traction. I swear I could a lawn with them the way it rips grass up.
I'm running Badlands on mine, with a 18t. Badlands are smaller then Trenchers X's though so I 17t should work. I've never had heat issues with my ESC, but I only run 4s.
