Could someone please enlighten me as to the reason(s), i.e. advantages and disadvantages of tracks that have full clipping or every 3rd window and same thing for single ply and full ply. I'm looking to upgrade my track on a 10 600 Shift. Where/how do I find the correct pitch, assuming that is determined by the drive gears on the shaft. I have been researching this for days now so if anyone knows of any web sites that have good info please post it. Thanks. Oh by the way 22 degrees this morning, no freaking snow.
