Well, like many things, this is all subjective. For me, in the last 35 years I’ve made only a few very small changes to things I utilize. For others, as is well documented on threads in this forum, they buy every new piece of equipment that comes down the pike. I actually find it comical looking at some players “load in” their equipment at the hall to play.
One thing I’ve seen to be a common theme, is that those with the most gadgets, or that always buy the newest thing, is that they tend not to play very well. That they might be better served taking a lesson or two from a top flight instructor than spending $750 on a new dedicated jump cue. At the end of the day it’s their

and they can spend it how they like. It’s no skin off my nose if they choose to be over equipped mediocre players. YMMV
