Never said he did.
But the way I’m reading that is he is making more power than the W2. Head material aside, we all know it is the port itself and the targeted goal that is in mind.
When you defend this guys use of an iron head, why is it he is using an iron head? Rules of the class?
I bet if the question was put to him, he would opt. for the aluminum for the weight savings because 50lbs. is just that much less to move down the track. If the general thumb of rule is upheld here, 100lbs. equals how much time? Yea.... I thought so.
