You should check out Greg's Right hand Drill. I would actually consider it a secret of golf in some respect because very few people do it. The ones who do and do it well ae the ones we watch on TV Thursduy thru Sunday. It is as Greg puts it. " the key to distance with accuracy, ungodly accuracy ". Since I watched this drill Greg (Willis) made I have never struck the ball so solidly and effortlessly. Now I can focus more on tempo and leave all the swing thoughts at the range. It's to the point now where if my tempo is on> I am almost guranteed to shot under 75. It's a great feeling. here's the link. Try to ingrain this and it in itself may fix a lot of your issues.
