Quoted from another thread, the official word from Shoe:
"There has been a lot of talk about the R1 Black not performing the
same as the other two clubs. I want everyone to know that the R1 Black
and the R1 White are the same. I have tested both out and the only
times I have found a significant difference in the distance, was when I
missed the ding or the ball hit on a down slope of a fairway and one
shot ran out. All other times the distances came out within a yard or
two of each other.
Now to he R1 Black compared to the R11. Again these are not the same
clubs, the differences are subtle but there are differences. The main
differences between the two is the forgiveness and slower swing meter
that the R1 provides over the R11.
Everything has been checked and double checked and the two R1's are the same and the R1 Black is different from the R11."

p.s. Just to add my own admittedly limited experience, I've played a few rounds with the new black R1 and it outdrives my R11s, but more importantly is more forgiving and sports a slower meter...very satisfied customer here, I was going to have to wait until after xmas to get the R1 at level 98.
