Try this experiment. Go somewhere where you can try a a lot of cues. Have some one put a bunch of cues together and hit a few balls with them. After doing this try to determine what the pins are. You may be able to tell what cue feels the best to you but I really doubt if you can can feel the difference that a pin size or material is.
Or try a cue that has a certain pin and then try another group of cues and see if you can pick the cues that have that pin.
