First of all welcome to the boards

Second of all if you havent taken a lesson lately, I'd take a lesson first, then get clubs. If for nothing else than to know that the swing you take with you to try new clubs is on the right track. It'd be a drag to buy a set, change/improve your swing, then find the clubs don't fit you anymore. Other than that I'd recomend Ping in the uber-improvement catagory. Either G5s, G2s, or even Eye 2s.
