Are you searching for the most forgiving driver? If so just look elsewhere. This TaylorMade R1 Driver is for players who have a consistent swing or are moving in that direction. I've had to work diligently on my swing to gain consistency with this driver.
The R1 driver gives good ball speed. My game is such that when I swing hard, I get poor results. If I go at 80%, I typically obtain very good results - with my swing speed, at best in the low 90's, I can pull out an occasional 250-260 yrd drive. The stock R1 is not the most satisfying driver in terms of feel or sound. It leaves you feeling empty in that regard.
It feels and sounds slightly better than the Titleist 913 D2 Driver, which felt "hard" and "direct" to me. My driver, as customized, is more pleasing as described above. I want consistency and a fairway finder with distance. That is more important than the "longest" driver although the R1 is long as I mentioned above. But you need to have a consistent swing that hits the ball high and center. Heel shots kill distance.
The newest TaylorMade SLDR, integrates a lower COG along with a brand new moveable weight technology to provide golfers even more adjustability. It works very well. So far, adjustable weighting systems on drivers have consisted of stationary weights. You can screw them in, screw them out, change from one gram-weight to another to affect ball flight.
The TaylorMade SLDR driver, however, using a sliding weight system - a weight literally slides across the bottom of the driver. Want to counteract a hook or draw? Slide the weight toward the fade side. Want to fight a slice? Slide it toward the draw side. The SLDR mechanism moves the driver's center of gravity low but more forward, something TaylorMade says promotes a hotter launch, lower spin and fast speeds off the face.
The R1 is a low spinning driver, depending on shaft, so it's okay to move up in loft and open the face angle. I am getting more enjoyment out of it as I improve and play. The SLDR weight can affect shot shape by up to 30 yards. I swear they would make you feel very well.
