The one I got to replace the factory slide (brand unknown) does pull the cables closer to the slide. I was shooting blazers also, and because of the issue with the factory slide the vanes were rubbing away at the cable whenever I shot. This caused a flat spot to be worn into the cables -- thank goodness I keep it waxed up or it would have been worse. Now the bow is so much smoother on the draw.

As a side note, I also switched from a whisker biscuit to the Bowtech Hostage rest. Seems great so far -- nice to have full clearance with the vanes.
