Ha I can my baseball swing pretty easily in my golf swing. I've taken years to perfect my baseball swing so I figured it would translate some into my golf one. I'll try out the drill with opposite hands tomorrow and see if it can fix me up

Edit:
Shade, I've been swinging a club around in my room with your suggestions about a solid base and the hips/thigh thing and it feels really good. When you're talking about the backswing and going after it I get a little lost. Are you saying to just shorten the backswing?
