Help.....
The last paragraph is the most telling.
I suspect that you are well past your football years so 391 lbs, is real big and there's alot of crap getting in the way when you swing a club.
If you want to swing in the 200's then you clearly have alot of work to do, but you probably already knew that. Take care of it it before it affects more than your knee.
In the meantime, take some lessons then take some more lessons. The best we can do on the internet is make simple suggestions. Having not seen your swing no one could know what your problems might be but a pro, standing there next to you will be most benificial.
Good luck!
