Maybe I shouldn't have used the words 'too much'. To me his going left looks good and fundamentally correct there.
But he said he wanted more power. So getting more weight forward will do that for him. His swing looks more like a
very safe rally ball and recover swing. Which is fine but I was giving him tips for power.
I think the bigger hitters don't go to the left as much as he does. They seem to be throwing their weight towards 1 oclock-ish (11oclock for lefties). More weight forward and thru and they use more ground forces.
even murray here who has a big rotation and ends up totally on the left seems to still have weight going more into the ball and then just continues around. His right shoulder is really going into the ball here before the weight swings around. That's what it looks like to me.
Now look at OP's swing. It looks like his whole momentum is going to 11 or 10 o'Clock before he even makes contact. http://www.youtube.com/watch?v=T3gwV-xlcNo
