I agree with John that it's not about the clubs as the pros can hit about any club as well.
I use Adams hybrids because they are ,imo,the best hybrids for me.But I also have an Adams sand wedge,and gap wedge that are just average wedges,but were priced nicely compared to Cleveland,or say even Titleist wedges.
I didn't buy them because Tom Watson endorsed them,anymore than Phil ,or Tiger would endorse a certain club.
For me,it's about which is the best club I can afford.
But then again,I'd endorse the cheapest box set of clubs out there if that company were paying me to do so.
