I know I will introduce the difference between R9 and TaylorMade R11 Driver today. But before that, I want to say something similar: they both have the TM 360 grip, they'll both be too long for you, unless you're very tall and have incredible hand-eye coordination. However, I do have found four major differences, just listed as follows.
Difference 1
The first difference comes with the size. The clubhead of R11 Driver is 440cc, while the R9 is 430cc. If you can tell a difference by look and playability, you need to be on Tour.
Difference 2
The second difference lies in the shaft. The TaylorMade R11 Driver comes with a stock Fujikura Blur 60 shaft. The R9 is a Fujikura Motore 65.
Difference 3
The stock lie angle for the R11 is 57*; the TaylorMade R9 Driver, 59*. Lie also isn't as important for drivers (because of its length, if the shaft is the proper flex it'll droop at impact in a "just right" lie angle) You could say that the r9 is more slice-corrective, because of the more upright lie angle, but all other specs would have to be the same.
Difference 4
The R11 also has that sole bumper. As I said, if you're properly fit for shaft flex, the lie at impact will take care of itself. If this is a big deal for you, so be it.
Other than the above-mentioned factors, there isn't much difference. The TaylorMade R9 Driver is a very good club... so why not game it? All you'd be "missing out on" (using that phrase lightly) would be 10cc head size, 2* lie/the sole bumper (see above) and a newer "it" shaft (no big deal)... oh, and a white crown. If that's worth an extra $200, that's your decision to make.
What Others Say About Them
"I think it comes down to how well you hit one versus the other. If there isn't a major difference, save a few dollars and get the TaylorMade R9 Driver. Both can be customized to fit your swing (the R11 more so) but until you hit both, it's hard to recommend one over the other."
"They are both great clubs... the minor upgrades between the TaylorMade R11 Driver and the r9 arent worth that much to me... i think we would all be suprised with the amount of circulation the r9 still has on tour... its still the best driver i ever hit..."
"The TaylorMade R11 Driver is a must have if you have been working on your game and wonder if there is something not right with your current driver. This club is the complete package of playability, distance and consistency, better than my previous R9."
Conclusion
Overall, I am not here to say which one is better, because they do have their unique features designed for people who suit them, though the R11 has been released recently and boasts strong technologies. This made many people forget the glory days of the early TaylorMade R7 CGB Max Fairway Wood, which was very popular in the past few years and still is. So I suggest that you choose which you like but not which others like.
