[O.B.Left]

There is more than one way I suppose. But I think the best way would be via EA in start up.

I might be over my head here but I think that if you start at fix you should employ extensor action (EA) prior to start up. A hitter would do this or a swinger starting in fix for say a chip shot , put or pitch.

The swinger would normally start from adjusted for full shots with the EA turned off prior to startup.

There is some middle ground too for the swinger, Yoda employs a sort of half and half , "attitude" for mid irons where he is between adjusted and fix with a little EA.

If you are a swinger try starting at the adjusted address position and employ EA during start up. If you are a hitter start from fix with EA already turned on.

I am assuming you use a right forearm takeaway here. A severe push away with the left arm or shoulder could I suppose cause what you are describing too. In that case the employment of EA alone will not give you what you seek. It may be a case for the turning off some old ways, muscles in addition to the turning on of new ways.
