Played some 8 ball with a guy who had a black stripe on his ferrule. I asked him what it was and he said he used it to help him line up shots. I have never seen such a thing. Is it legal? Sounds like a good idea.
I've never heard of a rule against it, and I've heard of players marking their shaft to know the orientation of the grain, so I think it's legal.
I REALLY CAN'T SEE HOW IT CAN WORK AS AN "AIMING AID"

It's basicly to see if you're twisting your cue. When the stroke is complete you look to see if the line is still on the top of ferrel. If it's not you're twisting the cue while you stroke. I had it on for about 10 strokes. I wasn't twisting and couldn't wait to get it off. Johnnyt
When I "discovered" this idea, I found that somebody had already patented it.

Interestingly enough...the cue I saw belonged to a diabetic.

I used this for several years. It helps in many ways for center ball aiming. It helps to keep one orientation for the cue stick to get the least deflection. I think it is an excellent training aid for a year or so to make the player focus on the stick line and the cue tip placement.
I used it in a pool league with several hundred players for a few years and was never told that it could not be used.
The front sight can be made with a red pencil and a ruler. The line lasts for a few weeks and then needs to be replaced. It wipes off easily.
Why would it matter whether or not you're twisting your cue?
