I really like my RS-X, but it goes just a tad bit longer than I like.  I did not want to take it to a heavy gritt surface, becasue it would just burn up.  I decided to experiment and had my proshop guy apply the Rough Buff just like on the Brunswick Absolute Inferno cover and BINGO!  It now reads the mid-lane big time and still turns the corner with all that .059 diff.  Still clears the heads very clean.  278,257,276 for 811.
