I have been running Bud and Lou on Clownshoes on my 9-0-7 and love them for the incredible traction but they do have a lot of drag on my speed. I finally got a set of Ground Control's this week. My findings are as expected. The Ground Control's definitely roll better than Bud and Lou however the traction on gravel covered climbs is not near that of Lou. Also in some very wet mud crossings my steering and rear traction was greatly diminished on the Ground Controls. Like I said it was as expected. I will run the Ground Controls when I feel I really need to go fast (Most of the time), and Bud and Lou when I think I may go some where that I could get in trouble. I need to get another set of wheels now so I can set them all up tubeless and just swap wheel/tire sets as required.
