their entire club sets every year like some. Seems like Callaway and TM have the "latest and greatest" driver or iron set released every six months. You buy one set and within a couple years they are already four or five models old. Hate that about them.

I like that Ping and Titleist will redesign a club every couple years or so kinda like a car company so you actually feel like you have the best technology for a while.

Plus when I see Callaway and TM stuff being sold at Costco, even though it's not their top notch stuff, it weakens the overall brand in my eyes.
