Compared with R7, I like R9 better.  The most advanced and finest performing driver in the history of golf club design per TaylorMade. The R9 will feature full adjustability in that it will combine 3 moveable weights with our newest technology-Flight Control Technology (FCT). FCT gives the golfer the ability to adjust the club head to affect face angle and loft. MWT and FCT give 75 yards of left to right adjustability, 3 degrees of launch angle adjustability, and up to 1800 rpm of spin adjustability. The club head can be rotated into one of eight positions, giving the ability to adjust from 2 degrees closed to 2 degrees open (actual measured face angle will be square to four open, though visually, 4 open looks 2 open to the golfer). This is done by a wrench and turning the club head onto the axis of the shaft. The three moveable weights are in similar positions to r7 Limited.
