I was only kidding about not wanting to improve. I didn't like the reply of basically "you suck, get lessons" so I came back with that. I do want to learn more but it seems like I'm incapable of it, unfortunately. I had a B+ player that was on my team for 2 years and we went to the pool hall together plenty of times and he would try to teach me draw, side english, and all that but I never got the hang of it. But he taught me how to play a very smart, defensive game which has pulled me through many matches where I should have had no business winning. Some people just don't have it in them to get to a high level in pool and I'm one of those people. But it's ok, I enjoy it a lot.
With all due respect, I agree with you that there are people that are unable to reach the level of an "A" player and especially pro level, but,
with that being said, everyone, and I mean EVERYONE has the ability to improve and improve significantly.
I know you have an itch to get a new cue, and that's cool, but nothing will give you more enjoyment in the game of pool than seeing your game improve, being able to controll the cueball, knowing what shots to take and in which order and what english to use.
Even though your friend maybe a good player doesn't mean he is a good instructor. I know this isn't what you want to hear, but take that money you currently have set aside for a cue and spend it on lessons with a certified instructor, then practice what that instructor taught you, 2 hours a day if your schedule permits.
Practicing correctly takes energy, focus, and the thought process of figuring out what you did wrong and tolerance for monotony and focus to practice that same shot to the point that you rarely get it wrong.
Once you have taken your game to the next level, AND YOU CAN, then reward yourself with a new cue. By then you may realize you want a different cue (weight, hit, wrap, maker, price) then originally thought.
When that time comes I would recommend one of the custom cue makers here on AZbilliards depending on what you like and price range.
Sorry for the long ramble and I certainly don't want to preach ,not my intention. You can greatly improve, you just have to want it enough!
