Personally I carry 1 driver, 1 3 wood, 1 54 degree, and 2 60's. Logic is that you might only use a hybrid once per round, but having a 60 degree that is only 60 yards saves many strokes on the course and I use it almost every time I miss a green. The short 60 degree requires a larger swing from short distances than say an 75-85yd 60 degree wedge, therefore it has a higher trajectory, stops much more quickly, and allows a much higher level of distance control. In my real golf bag I carry a 52, 56, and a 60. At least 1/2 of the pros on the PGA carry a PW, Gap Wedge, SW, and lob as well. You should find a substantial decrease in greenside bogeys with a similar set up. Why carry a hybrid for 1-2 shots on the course when there is a potential on every hole to miss the green and have to scramble to save par? BOGEYS kill!
As for 2 drivers, I'm not quite sold on that. It seems a person could use their 3 wood for a tight fairway they need to hit and still have the versatility to use it in other circumstances on the course, like reaching certain par 5's in 2 shots or the absurding long par 4 at BPB (#7 i think) in regulation.
Hope this helps. Good luck!
