If a player has never felt , or been aware of, lag pressure... Is it easier for them to recognise a large amount of lag pressure or a small amount of lag pressure?

Doesn't matter, as long as there is "lag".

Whilst their technique may not be adequate to sustain large amount of lag pressure ( throwaway and poor structure) is it not better that they really feel what they have got to sustain?

There is very little technique needed to "load it and sustain". Again, it's in the intent.

Do heavy clubs work this way? Give the player a massive dollop of lag pressure in transition phase that then allows them to recognise the more subtle flavours of lag pressure with a normally weighted club?

It should, given that the player has no intent to "throw it away".

It is hard to sustain something that you are not aware of...

Very true. Yet, it's even harder to sustain something that you are so eager to "throw away".

There is one way for you to experience the "LAG/hands-controlled-pivot":

First, you need to establish the "lag"/resistance/heaviness feel/drag ("artifically"). Take the club back to the waist level so that the shaft is parallel to the target line and the ground and have someone hold it firmly behind you or tight the clubhead to something stationary.

Next, pull or push the club (toward the ball as in your normal swing) with the hands. The resistance/heaviness feel/drag your hands and body encounterring (or the shaft bent/stress created) is THE "Lag" (you are supposed to feel during a "lag-sustaining" swing). The harder the action, the more the "lag".

Now, look yourself in the mirror (or shot a video), if it's available, how your pivot react/respond (or being controlled by) to your intent of pulling or pushing against the "lag" with the hands. Yeah right, all of a sudden that familiar "bump and turn" you hear all the time comes up. Also feel the tension created all over the body (the pivot lag, accumulator lag and club lag).

How come you intend to pull or push, yet the pivot always shows up first with a nice little "bump and turn"?

How about the "pivot-controlled-hands"? Just try to move the club with the intent of bumping and turning the pivot and look into the mirror. Now, compare the difference in body motion and feel created between those two "intents".

Hope it's clear enough. Good luck and enjoy.
