I really like my Tracks.

Mine is the Sherlock model. They have had a lot of hard use and are still as good as new except for some minor scratches. The rubber tips screw on very solid and can be removed if one prefers to use the spike (as in icy conditions). To tops remove to allow for camera attachment. They are very adjustable and sturdy. I don't know how they compare weight wise but I like mine. I have two of them.
