6bee, here is my reply:
First, you demonstrate again you can't anwer my posts without ad hominem attacks.
Second, to the specifics. Neither the left, nor the right HAVE to be completely straight at impact. Neither do they have to be completely bent.
Third, you state: <Some, from the Mark Evershed school don’t ever straighten the bent right wrist even after impact- like a tennis shot- and have tremendous impact. Wonder why?">
You seem to think this is a novel idea for me. Perhaps I even prefer to do exactly this. Understand? While you and I might prefer to do something, that doesn't make other possibilities...IMPOSSIBLE or even quite workdable. Again, the Fallacy of Extremes.
You also fail to realize I never said the right straightens 100% before impact. I said it is STRAIGHTENING. THE ANGLE IS BEING REDUCED. HOWEVER, it can go to effectively complete straightening:
1) before impact
2) at impact
3) after impact.
The consequences depends laregly on timing.
Look at it like this: if a boxer throws a straight right, his arm goes from bent to straightening. You don't think it will hurt if that punch straightens after impact, at impact or before impact? To deny any of these is to deny the right as power accumulator. Your chin might not
agree. Should we meet, I'll be glad to demonstrate any of these, in case you insist only number 3 makes sense.
You further stated: <The right hand is the clubhead- it drives down, out and through. It remained bent at impact driving down the plane line.>
The right hand does not have to drive down, out and thru. It can be the left doing the driving, amongst many other possibilities. I'm sure you know this, but you statement is also imprecise for other reasons. Namely, even if we are talking about an activated right hand, it does not have to drive out. It can drive down the line or even in, depending upon the swing model and the desired type of ball flight.
Lastly, your statement: <Any swivel or roll is because of the left hand.>
That is simply false. The right hand can start the roll with the left following, as opposed to the other way around. Indeed, several possibilities exist:
1) the left wrist causes the roll
2) the right wrist causes the roll
3) both wrists roll approximately equally
4) both wrists contribute to the roll, but disproportionately
5) the wrists roll for other reasons
Other possibilities exist, but I'll stop with 5.
I have no idea what HK says about this, and I really don't care. The reality is, there are many ways to impact the ball and and to provide power. Because THAT is true, your argument against #5 and #6 fails.
Next...
