Spammage: there are only a couple of drives in a round where I can tell that having the R1 gave me any advantage of the R11S.
This will change as you play the different courses over and over. A lot of holes have become driver/wedge a la the TM days. What I find interesting about the R1 is the way it changes the way you think. The wind has a different affect on the flatter trajectory , the roll after landing is better and the accuracy will let you actually chose spots to land on to increase the drive, like a back slope with top spin. 340-360 drives on the links courses happen more frequently.
It's not really a game changer, IMO, but it definitely is a thinking changer. :-)
