Try to go into a fitting with no preconceptions. You may hit blades well, but the fact that most pro's don't play blades anymore, should be an indication that there is maybe something to more modern cavity backs. At the very least consider a combo set. Even if you look at the most basic of cavty backs, such as the Titleist T100, Mizuno S3, Ping Blueprint S, or some Miura's or Vega's. And if the offset and lofts are a bit strong, by weakening the lofts it reduces the offset.
Woods, everything is pretty good right now, but I am always a believer in buying the latest model. I've persoanlly had best results with Ping G440, but Titleist, Taylormade, andCallaway are all really strong. Cobra Srixon, and Wilson are hanging right with them too. Hybrids I really like Titleist, Ping and Srixon.
Wedges it comes down to grooves. If the grooves are still sharp then stick with them. But if not, change them.
Your putter is the one club I wouldn't change. But I am biased. I think the Barbados is one of the best putters of all time, and would still be using one if it wasn't stolen out of my bag. They were ahead of the curve with a grooved face. But putting is so personal, if you fancy a different one then why not.
