I agree with the previous post.
One thing to consider is, if you are hitting a pitching wedge 140-150.. maybe you are trying to swing too hard. As a beginner, distance really isnt that important, your primary goal is accurance/consistancy. I suggest slowing things down a bit, and taking a lesson or two with the local golf instuctor. I have been playing quite a while now, and although I can hit a pw 150, in order to have consistant distance/accuracy control I must focus on a smooth swing. I think you will find even if you dont hit as far, you are better off slowing things down, keeping it in the fairway.... Good luck!! and welcome to the hardest game you will ever play..
