So I understand the different grades of shaft woods. AAA I guess is the best. Is there a huge difference in prices from say a to aaa. Not asking for anyone to divulge their prices but is aaa like three times more than a? I understand that a $300 stick may not warrant your best shaft wood, but at what price should one expect the best shaft. Why not just try and buy the very best and pass that on to the customer. Doesn't the better shaft wood have fewer issues with warpage? I guess I'm asking for a tutorial on shaft wood? Thanks.
