Re: Do you really need a driver in your bag?IMO, you don't NEED a driver, but if you aspire to make it to a low handicap, you'll eventually find that you really wish you had one you could hit. In my case, I'm a high enough handicap that I probably would do as well or better just to forget about the driver, and possibly even the woods, and play 4I or less off the tee every time. It helps that I play a short course (9 holes at just under 3000 yards from the longest tees). In fact, the last time out I think I only hit driver on 3 holes.
However, if you can put the driver in the fairway or playable rough most of the time, those 20-40 yards versus your 3W do make a pretty big difference. On a 400 yard par 4, if I find the fairway with my driver, have a shot at the green with my irons. With a 3W, I'm probably looking at a 5W or another 3W to get there, so unless it's wide open around the green, I'll most likely lay up and play for bogey. Even if I miss and have to chip out with the driver, I'm probably not a whole lot worse than that --- between the extra distance on the tee shot and, with luck, some forward progress getting back to the fairway, I probably still have a pretty good chance to reach the green in 3.
So I guess what I'm saying is, no, you certainly don't NEED one, at least at my level where I'm thrilled to hit mostly bogeys. However, if you play a medium to long course, and have at least fair control over it, the extra length can make up for some of the trouble it may cause. I think that's especially true if you don't expect too much and let badly-missed fairways make you angry-stupid.
