Hi Will,
I am with Lynn - while clubhead speed seems to be the difference, I believe what you are looking for is power. Impact can result in serious deceleration!!!
Personally, I would look at the uncocking left wrist for speed and make sure you have a bent right wrist at impact which will ensure you have what Lynn called effective clubhead mass. As Lynn stated, when you throw the clubhead at the wrists, clubhead speed is accelerated - but at a cost. First, the bent right wrist is now flat and can offer no resistance to ball/face contact and the clubface is now moving in an upward direction, nullifying the how the face was meant to be hit.

Great question! Love the thread!

Thanks, Philly. Just tryin' to learn!
