You wake up in a parallel universe tomorrow where you can only play with seven clubs. What seven would you pick? Any reason why you'd pick those Seven? Here is my break down in no real order:
Putter-Can't Golf without it.
Driver- I use it on all par 4's and 5's
Sand Wedge- It can also be used for chipping and pitching.
3 wood- I have a high lofted 3 wood and for no real reason I'd pick that over my 5.
4, 7 & 9 Irons
