Atlasman, I checked my patriot this week and found that BOTH of my rollers quit rotating. A build up of wax tipped me off that something was amiss. I trimmed and lubbed but the best I could get was for one of the rollers to turn.
I then drew back my stalker and only one of the rollers was rotating on it.
This got me[:@].
I replaced the gilde slide with a new saunders (tephlon w/ roller) and the speed was the same, but it pulled the cables too far over IMHO.
I tried a simms and the stock slide and both lost my set up 1-2 fps and the noise created during the shot sequence got louder than compared with the glide slide.

I called alpine and explained that I wanted to use their slide, but BOTH were not working properly. The one on the patriot experienced a stretching of the axle hole in the rubber for the rollers as it is no longer round, but elongated.
His response was curious in tone as if this was the first time he had heard of such an issue. He said he would send me 2 new slides as long as I returned the two non working slides so he could look into them.
Unless they redesigned them somewhat I can only see the same thing happening with them.
I guess I will order a hicks or bohmer and use the alpine until it quits working again.

For those using Alpines- check for proper rotation.
