Sam's carries the old Nike driver, the TM 300 series, and a combo TM 420 and tour spoon or raylor. I bougt a 4 wood TM at Sam's and think it is a great club.
The TM 300 series of driver was a big flop and I would avoid it and go with the 500 series, which is a big improvement according to most.
But, I reiterate my suggestion that you try the Cobra 440SZ. It is flat out a cheater club. I used to be a 225 guy, and now I am a 285 guy. Most of that is the confidence to turn hard on that beyotch because the face is the size of a dinner plate.
I still have some old drivers but I keep them around to make sure Mr. Cobra knows he is subject to being fired at any time.
