There are differences between cues..Anyone who says otherwise is a moron who should be ignored! It doesn't mean that more expensive is better, but some cues will be better suited to you than others. I like a very firm hit and I like the energy to be transmitted to my hand for a nice feedback. At the same time I don't like a lot of deflection. My Mezz serves me well, but could be considered an expensive cue by many players. I tried for 6 months to get used to a cue with high deflection, but I just couldn't do it. I played at maybe 80% of my skill level at best with that cue. That was not just in my mind, the statistics showed it!
I never understood the "reverse snobbery" in pool. "I ran 2 racks with a housecue that was bent and had a bad tip". Well, that's good for you, meanwhile you lost the match to someone with a proper cue. Housecues can be ok, but at least make sure the tip is good, if not fix it up with a tip tool. I don't care that you can play decently with a shabby cue. I care what the best you can do is. There is no heroism in playing with a cue that is bad, when you can easily afford a better one. To me it's just stupid, and shows that you are not serious about the game. It's ok not be serious about pool, but then you shouldn't be bragging about your exploits either!
Also some people think they can "police" who buys what cue! If some bad player buys a nice cue, that's no concern of yours! Also at what point do you "earn" the right to own a nice cue? Do you have to run 5 racks of 10 ball? 100 balls in 14.1? 200? This world would be better if certain people worried more about playing the game than hating on people with nice cues. Since Efren played so well with a 15 dollar cue, that means that nobody can ever own a more expensice cue right, that's the logical extension of the argument of these people? Also what you are in fact saying is that there are differences between cues, that better players should have better cues, so in fact you are making the argument for the other side. What if the same sort of argument was used on the amount of training? "Well I lost only 8-10 against you, and I've been playing for only 2 years, while you have played since childhood, therefore it's a victory for me!" The whole thing is just stupid and makes no sense at all.
