right about them being the same thing... warn makes them for polaris so go with whatever you find a deal on... and synthetic rope or nothing. its stronger, tougher, and spools better. PLUS it is much easier to fix on the trail if it does get damaged (buddy hit mine with an ax while it was around a tree). Only draw back is that you should not use a snatch block with them (but can if your careful).
