Pretty much said what has been posted. Most peeps don't use or understand 20 clicks of adjustment so now only 3. I guess I agree somewhat 20 too many but maybe 5 would be better 3 seems very limiting but won't know for sure until one fools with it for 100 miles or so in different conditons. More so I question doo adjustable carbide might be clicking that thing all over the place & get nothing for your trouble but a flat costly carbide. lolI am not a subscriber to american snowmobiler, I wish I could read the article.,
