When I damaged my small headed Tommy Armour driver I was left hitting off the tee with a new 3W I had in my bag. Now my driver was my first non-wood driver and I seemed to be more accurate with it than hitting the old persimmons. The metal 3W head was somewhat larger ( I don't know the CCs) and the shaft was more flexible than the driver's shaft. I noticed that the 3W became more consistent for me and distance was not suffering all that much. As a result I used the 3W exclusively for a couple of years. This year I purchased a 460cc headed driver. On the practice tee I felt uncomfortable looking at that huge head. It reminded me of those plastic kiddie golf sets with the huge red plastic head. Anyway, aside from this, using longer tees was a must. With the new BIG driver, my distance is slightly longer (when I hit it) than my 3W, but my swing is not as good with it. I seem to be pushing the ball to the right. (Instead of 12 o'clock, perhaps 1 or 2 o'clock). This tells me I'm not coming around on the ball as well or addressing it correctly. The shaft is similar to the 3W. Consequently, my confidence remains stronger with the 3W off the tee.

I suppose if I were to spend time practicing with the driver I would soon learn it's differences and then I might be able to alter my swing or address just a bit to get it to fly straight. Golf is a very tough game to master isn' t it.
