(Excuse me if I ask too many questions and just ignore if that's the case, I'm not the best golfer on here by any stretch of the imagination, but I am a club geek and love talking about this stuff). Ok, so you're hitting what for hybrids and which irons (4-pw?) I'm not talking so much brand, but lineup? Are you at a full 14 clubs or could you add one? Why do you want to get fit for a new set? What part of your game costs you the most strokes - off the tee, approaches, around the green, putting? RBZs are relatively new tech and you might be able to do a simple bend or lie adjustment to tweak if you feel like you're not hitting optimally. If you hit your full swings well and it's 150 in that's causing you issues, as CL noted, being able to take a full swing would be really helpful. And those are some big gaps in yardage for PW-SW. You could mitigate by planing your way around the course smarter - if you have choice of hitting a driver to leave you 115 yards in for a half pitch you struggle with, or a hybrid to leave you a full PW in, go with the latter - but you can also do both. Unless you have an itch for a new set, I'd get a simple lie and length check (or you can actually do this yourself with contact tape and a piece of plexi glass, there's plenty of videos out there) and get them bent if need be. Buy the gap wedge for your set (50* - used sites, eBay, there's sites where they will literally find a particular individual club if you lose it, etc}, drop the 52 and sand and get a 54/58 or even a 56/60 sand/lob setup. I like knowing I can take a full swing and it's only going 85 yds. I'm actually debating adding a 62* if/when I get new clubs and dropping my 5 iron. The new 5 irons are the same degree as my current 4, which I don't use. So why not add a club I can take a full swing on from 60-65 yards instead of carrying dead wood? The rest of the season try to make a note of where you're losing strokes, what type shots, at what distances, full swing or trying to 'muscle up' or hit a half shot. That should help tell you if it's you're gaps that are costing you strokes or you need new sticks. If you just want to burn money on a fitting a new rig, I'm not one to judge I blow money in clubs every year and I don't play enough to justify it.
