well I'm probs in a good position to answer this, having only yesterday bought a new driver from my old RAM
whatever people say, equipment does make a difference, but make sure its something that you're comfortable with, try and go to a shop to try the clubs out. I tried both Nike Sasquatch Sumo's, Taylormade Superquad, Callaway FT5 and in the end settled on the Sasquatch Sumo 1 cos I hit it the best and felt good with it.
Point is, try the equipment first because different swings suit different clubs. (but my new Nike is amazing as well
)
