I ride in a cart 100% of the time, and I need a towel that drapes over the back basket but won't fly off. The N52 industrial magnet on this is scary strong. I hit a nasty curb at full speed yesterday and my rangefinder fell out of the cubby, but The 40 was still locked onto the cart strut. If you are a cart rider, do not get the smaller towels�get this one for the extra surface area and hold."
