No cue will "limit" your ability.
People today will push low deflection shafts and the highest priced layered cue tips, but the simple truth is before any of that ever existed there were
players who could run balls all day and make seemingly impossible shots.
Having something expensive that stands out and makes you feel confident
will make you feel better about your game but the price of a cue shouldn't matter all that much. If you possess the skills to be a top notch player then yea it may make a difference but even then you should still run racks with even a bar cue.
So I guess to put it simply, if you really want a new cue then do a little research and see if you can borrow someone elses and test hit it a few times to see what YOU like.
