I had the R11s and it would carry the bunker / rough complex on #9 at BPB and get you into the fairway with an open shot from about 135 to the green. I believe that the R11 would get you there as well as long as the wind was under 5 mph into you.
The R1 is much more foregiving that either version of the R11. It is also longer by somewhere between 3 and 15 yards depending on conditions. Since we don't have a driving range it is tough to test them against each other with perfect conditions.
I wasn't sold on the R1 when I bought it but I had extra credits and noticed that all the best players were putting it in their bag. I bought it and except for a few shots on the course that are tough with it (BPB 2 and CON 4 for example) I have been very pleased with it.
I consistently can get to 300 yard average in a round and using b/s and t/p I can work the ball to may advantage in the wind. Had I known it was available to me, I would have skipped the R11s step but all in all I'm happy with it
