IMO the Surge SS is the Rogue in FLX plastic. They fly exactly the same for me except that the Rogue skips a little farther than the Surge SS. I didn't find the Surge SS any more stable than the Rogue, eventhough some FLX discs are a lot more stable than their counterparts. I have a red standard production stamped Surge SS and two from BG AMS, no noticable stability differences. maybe someone else can clue you in on color differences better than me.
It is not just your opinion, that is a FACT on the SS Surge/Rogue.
