Wrist setting, early / late - Does it matter?

wrist set needed as that sets one of the levers to give optimum speed through the strike for the swing motion.

for such a 'small' physical movement with the lead wrist/thumb (assuming it's done correctly the 'set' being 'upwards on the snuff box joint) it moves the 'clubhead' over a larger distance more quickly both to the top of the swing & then from hands very near to the ball moves the club head again over a larger distance but now real quick.
the lead hand setting correctly on this joint at bottom of thumb also helps set for most folks - & would help most folks set who currently aren't doing this - the club shaft on plane.

thing a lot of folks miss, (as their check for 'lag' is solely on what the lead wrist, so lead arm is - in angle relationship to the shaft) is they pretty much miss what the trail hand/wrist/arm is doing in relationship to the shaft & stored energy, so lag.

most teachers would say the trail hand/trail arm relationship to shaft (lag) is in many respects a good ways more important than the lead.

always difficult when using very individual swings as a marker to what happens, what should happen, what shouldn't be happening in 'any' other folks swing motions.

Jimenez has a very 'individualistic' swing motion. what a lot of folks miss is what is happening to his right hand/arm during his swing motion, & when it's happening.

if you look closely at the dtl driver swing at 0.07' you'll see him 'hinge' his right hand back on itself markedly so very early on there's a pretty big angle being formed between back of right hand to right forearm so to also the shaft. also the right elbow is starting to fold very soon in the motion, so there's also an early angle relationship between right forearm to shaft (you'll also see this in the face on slowmo vid early on around 0.13')

so this 'right hand/arm' all gets 'set' real early on but in doing so it keeps the left arm & wrist a ways 'straighter' longer only setting the left later on.
but most of the arm/hand speed in the motion he can get in his motion is coming from the angles set early on in the right hand & arm. this is also why he swings the club on the 'plane' he does.
