my R11 is being out driven by R9s all the time l88)
As YJ says, a bit off topic but I'll add my tuppence worth since I notice this too sometimes.
I have the L80 R9 and frequently outdrive players with the R11 when using the same ball. I would say it's when playing into a headwind or, maybe, crosswind. The high flight of the R11 lets the wind effect the ball more. With a tailwind forget it, the R11 easily outdrives the R9.
Sorry for the interruption, normal service can now be resumed.
