The OEM success centers around hype, marketing and what is on tour. However, within the hype is some truth.
Bottom line, OEM or component, there is a club for everyone by matching the correct head and shaft. Does it matter if it is OEM or component? No. It's what works and fits your budget and not your ego or desire to look cool.
As a mere mortal golfer, not to disrespect this tour, but I find more interest in what the LPGA players have in their bag. Distances and SS are closer to mine and also more hybrids and higher lofted fw's are there for a valid reason.
