Wanole, like you, I've been practicing the basic motion alot. Just a couple of extra tips. 1) Make your motions very slow and deliberate. That way you can identify when you lose your flat left wrist/bent right wrist. 2) Look at your hands first, and not the clubface/head. That way you can more closely identify what you feel and what's really happening. 3) Use dowels and not a club. The relative light weight of the dowels make me really concentrate on creating and feeling the lag pressure (which is harder to do when there is less inertia at the end of the shaft). 4) Use a putter. Once I've got the feel of the lag pressure, I use a putter. The flat face on the end of a putter helps accentuate the visual of the hinge motions. Plus the flat sides of the grip help identify "aft" where you should place PP#1 and 3. Good luck, I'm there with you.
