I’m going to assume you meant your skill level is close to @Hackasaurus Rex, since the OP is a 5 handicap.
Anyway, it really depends on what clubs you currently play and how old they are, as well as your skill level. What exactly is it about them that you (and others) feel is holding you back? If you feel like you should get an upgrade as a high handicap player, most people would point you towards previous model year clubs. They will perform similarly to the latest releases, but they’re cheaper. Depending on your skill level, you might not need a tour-style fitting, as a lot of that has to do with finding the exact combination of shaft and heads to fine tune performance. A properly fitted club can only do so much if your ballstriking isn’t very consistent.
