I've been looking into getting a couple sets of "J Style" roof top racks for carrying my two sea kayaks. I've been using a Thule Slipstream but have decided to sell it and go to the J Style so I'll have more room for transporting my boats on my car's factory cross bars ('12 Nissan Murano). I've been surfing Ebay and Amazon and have found these, http://www.packemracks.com/pkfostjrorap.html
. I've not been able to find any paddler specific website reviews. I suppose these are relatively new to the market. Reviews from Amazon all say about the same thing, "Foam padding comes off easily and the cam straps are a bit of a pain". I see these as easily remedied but just want to know if the cradles themselves are durable. Any input would be greatly appreciated.
