The first thing is to realize there are no "dumb" questions. Ask as many and as often as it takes to learn. If you don't get an answer to your satisfaction, ask someone else. And always get another opinion. And then, test the answers which you find most accurate. Having only three years under my belt, I found this to work for me.
When I first got involved with this game, I didn't know what clubs i wanted, nor did I want to commit a lot of money. So I went to a clubmaking class @Golfsmith, bought some components, and a few tools @Home Depot. I then built a steel shafted set consisting of a Driver, 5, 7, 9, PW, and SW. I bought a used Nike 18* CPR hybrid, Golfsmith 3w kit and a new Odyssey 2-ball putter. Spent about $285 total. Still game this set from time to time. But this is what i used to ldevelop my love for the game. I patiently waited and got the TM R7 XD's that I really wanted. Mind you, by learning to built my own sticks, I am truly a charter member of Club HO. But that's another story, for another post.
The suggestions you got about being fitted are true, accurate, and both time and money saving advice. Give yourself a day for this, and test every club which interests you. I also suggest you take some time with this. No quick decisions here. Go back and try another day. I've found golf to be a game of good days and bad days. So go to the shop and test the clubs you like 2-3 times before buying. IN addition, research the sticks you find pleasing to the eye, and check the lofts of the set, committing the 6-iron lofts to memory or paper. These are the most common demo lofts. While shopping, ignore the sales pitch and brand name at this stage. Instead, focus on those clubs that fit your eye, swing and offer consistent performance. If the clubs that fit you best are outside your price point, WAIT-NEVER SETTLE. Don't worry about sale pricing-there will always be a sale somewhere. Just remember, steel shafted is always cheaper than graphite shafted.
In short, you've already got some sticks, so don't make a knee-jerk purchase. Take your time, get properly fitted, and get the sticks that best suit your present game. You won't be sorry. And if you're catching it for your non-OEM sticks, remind that cacklers that Zevo, Lynx, Dunlop et al, have been gamed by some of the best-and have Major Championships under their belt to boot. Fred Couples and Tom Watson gamed Lynx clubs and won majors with them! Good luck, Bruh.
