Playa', you think Cleveland approached Miyazaki and said "Hey, we'd like for you to provide us with all the shafts for our new Classic line of drivers"
Miyazaki replied "That's fine, but we only make .335 sized shafts and we won't change that for you".
Cleveland: "Oh, not problem. We'll just shim all of the tens of thousands of clubs we manufacture because we really like you guys".
Did it ever occur to you that maybe Miyazaki produced a grouping of shafts specifically designed for the Cleveland Classic series of drivers? And that maybe this particular grouping of shafts is .350 rather than their usual .335? And that maybe that grouping of shafts is different than their normal line of aftermarket shafts?
