Getting away from the single play / unlimited debate, one random player from each tier is going to win an R11 driver.
Most Legends (and Tour masters) already have the R11 in their bag.
The Hack who is lucky in the draw is going to have a huge advantage for the next 4 months as nobody in his tier will be able to drive within 50yds of him. Unless of course it's that lvl 90 Hack who never plays stroke play (only MP credit games), and he's likely to have the R11 already too.
