I use a 10 degree driver(have been for many years) and was looking to try something different. I told my buddy I was going to get a 9 degree and he said I would slice with it because of the lower loft. Does anyone know if this is true and why? Not sure if this makes any difference but my swing speed has been clocked in the 120's. I would imagine that it gets slower as the day progresses(sp?). Thanx for any help!
