i agree with you, that is another way. in relation to that, do you think the position in space of the left elbow and wrist is any different for the strong grip player that chicken wings and someone like trevino who clears aggressively to the left? if you put yourself statically in the position of the left elbow away from body player (chicken wing) and then fill that gap with the body while leaving the elbow out there so the arm is again close to the body, it starts to look a bit trevinoish i find. so, either get that elbow forward independently or use the body to get it there. but make sure you get it there or else you'll have to manipulate the hands or keep your address hands through a bend like Jim suggests.
i think i agree with you matthew.
someone with a strong grip has to holds the face open some way. there are different ways of doing it. the most common way i think you see players on tour do it is by hanging back a la rory sabbatini. this again alows the left elbow to face the target a little longer, which i spose yu could say is the ultimate goal of a strong grip player, as if the elbow starts facing down to the ground more, the ball is goin left.
if you watch slo-mo of zach johnson you will see how hard he works to stop the blade turning over. he keeps his left arm almost totally straight after impact. thats one way to do it.

you can also see how much and how quickly his body turns through the shot. this is something you will see with strong grip players. trevino obviously did it, and duval did it so much, thats why his head turned through so much, so it didnt inhibit his body getting out of the way
