My estimate (R11-S and top RZN dist ball) is +5% give or take. R11-S 3W & R11 long irons about the same; that tapers off a bit as you get to the short irons - 8 - PW to +3% give or take.
All that is relative to Pro Shop rated distance, and 'neutral'' (centered dot) spin. Because both the R-11 clubs and the RZN ball have good spin characteristics, I only make minimal spin adjustments, unless circumstances force me to manipulate the ball a bit more.

alcaucin:
What about with the new RZN Nike ball, anyone charted that yet ?
Thinking of changing balls as looks like PP will be up and running before they put an extra dot on the Max (the forgotten range) :-)
