Sean,

I am not a professional by any means, but in my experience when I keep my right shoulder high at impact it helps keep the ball lower because it de-lofts the club at impact.

Yes, it's true.  This is something you will hear Tom Watson talk about all the time.  He spent his career with a high fade with a reverse C.  His misses were usually short and right.  Around the early '90s, he says he found something that would have helped him a great deal in his career:  Raising the right shoulder.  This produces a lower ball flight because it angles the clubface downward.  Another term for this is "trapping" the ball.  It works.  You should consider purchasing his instructional DVD (which can be found at http://www.tomwatson.com/ ).  It's some pretty great stuff.  Funny thing:  A PGA pro was giving me a few lessons.  I was hitting the ball really, really low.  I told me to raise my left shoulder and drop my right.  Quickly the ball became airborne.  One of the reasons this works is because that the head gets pushed further back as the shoulders tilt.  The ball flight is determined by where the hands are in relation to the ball, and where the hands are is determined primarily by the position of the head.  This is why positioning the ball position further back in the stance produces a lower ball flight.  So if you want to hit it a little lower, you can adjust the position of your shoulders, your head, or your ball.  Of course, sometimes the reason for high ball flight is that the player is not shifting their weight all the way left into the downswing.

Hope this helps,

Probably the best thing to do is visit your local PGA Pro for a lesson on this...it is my experience that they will get you where you need to be on this point quickly and without making lots of errors that may mess up the rest of your game... JAT

Cheers guys, thanks for the confirmation.

I've a habit of messing with my swing sometimes and throwing it off kilter, and didn't want to start practising something before I knew it would work.

Thanks again, Seán
