I had the 280 yard R9 and although it does 'keep up' with the R11 when you are into a fairly heavy wind, it can't compare to it with a still wind or downwind. The R11 is very precise, you can fly it to an exact yardage without relying on the roll to get there. It makes it so I feel I can take aim at a target on the fairway and put it there. I had bought the R9 prior to the R11 coming into being and of course got the small trade in. My opinion is that if you are at the level 80 and have the R9 (lower version) wait to get the R11, those 8 levels will take a while but are well worth the wait.
