BFG R1 vs R1S?

[backformore]

Thanks Marty. A slammin deal in a set of R1 made it a moot point for now but makes me want to try the S for the next set.

After winning a couple Majors races this year on the R1 (all the fast guys broke. HA!), I ordered up a set of R1S. They lasted me two weekends before cording whereas I still have some of the R1 I bought two years ago with 8+ weekends on them. They're getting slow and hard from cycles, but they still have rubber on them. The R1S is definitely faster, but they wore like an R6.
