Although I'm a Callaway guy, I'd still choose TaylorMade over Callaway. Why? Simply because they're #1 driver in golf. Ok, that's ad talking. Anyway, I love their MWT technology - the ability to shape your shot. Btw, I'm currently using the r7 460cc. Although it doesn't have too much option in changing the result (only straight or draw due to only 2 ports available), but it has helped me eliminate the slice most of the time. A close friend of mine, however, has the r7 425cc. Now, that's the club I'm talking about. It can actually adapt to your current swing. With the stock weights (2-2 grams and 2-12 grams), you'll be able to choose whatever kind of result you're looking for (draw, straight, or fade). But if you decide to get the weight kit, the possibility of different trajectories are even greater.
And now, TaylorMade has the r7 SuperQuad 460cc with 4 weight ports. In other words, r7 425cc and r7 460cc live together in 1 black painted house (yes, the new driver is all black).
So, if you're looking for those kind of features, which I am, TaylorMade is for you. Like I said earlier, it is the #1 driver in golf.
