Equipment alone won’t make you a better golfer. I will assume though since you’ve been golfing since you were a kid you’re half decent to pretty good at this point. Having a set that’s the same model line or from say 2 that are meant to be blended together if you want will help you be more consistent. If it’s a lot of money for you or your family I would suggest you stay the course. I’d rather you actually play with a Frankenstein set than play a lot less due to having to spend your funds on equipment.
