TrackLug Studs

[It sleeps in the back yard]

Has any one used tried these "screw in" studs, Also what do you think about them.
* are they worth the time And $$, or would they just get ripped out?*

These are suppose to be great. Talked to the owner of C&A and he said that they save wieght(also HP), and give better traction on 1" and deeper lug tracks. Suppose to be able to run less studs and they wiegh less. This means less rotating mass and equals more usable HP. As for anyone that has used them on the trails I don't know of anybody yet.
