What retractable tonneau covers are people using on their 2015's?

I am leaning towards either a Retrax MX or a Pace/Edwards Jackrabbit. I am a little leery about the polycarbonate construction on the Retrax and their aluminum Pro versions are a little pricey. They do have the roller bearings to make it slide better though. The Pace Edwards one is aluminum with a padded top laminated to it. But it just utilizes a teflon coated track that I would assume needs lubrication along the way.

 

I have had 3 Retrax. One was the Pro version and it is way better than the standards. I have had two of the regular ones and the last one cracked at 2 years old. The one I have now is much harder to open and doesn't seem to work as well. I think it might be more about installation than product. They will warranty the tops for cracking, but I didn't do it because I was getting rid of the truck. With the topper on there and closed, it still leaks a little bit, and the dust is pretty bad as well. Thats more of the bed having so many holes in it and not seam sealed.

 

I went with a Paragon.
