I've been kind of getting into pool more and I read where your shooting hand grip should be about one inch behind the balance point of the cue. If that's true, I think I habitually hold it even farther behind than that. Got me to thinking, for consistency, do some cues have a ring or some other marker to indicate balance point? Dumb question? Or does it matter... do you vary this grip spot quite a bit? This also brings up cue length. I tend to like longer cues I find on the barroom wall. I am 6' 2" tall, does that matter? What length is 'acceptable?' Thanks.
Where you grip the cue depends on how comfortable you are with the stroke. One thing you do need to make sure is that your arm can freely move and stike the cueball at the right point of the swing. A lot of new players start their stroke extended, and when they actually contact the cueball they are hitting it at where a normal follow-through point would be. Also keep in mind for house cues, a lot of them are pretty short, many under 58" which is the "standard".
For a taller person with longer arms, a 60" cue may be normal to use, and a lot of shorter players use longer cues now.
I don't know of any cue with a mark at the balance point and I don't think it would matter since where you hold the cue depends on your personal stance and stroke. Not sure where you read about holding it an inch behind the balance point, one inch behind the balance point in most cues would be right on top of the wrap area, and I don't know anyone that chokes up on the cue that much. Most players hold the cue no closer than middle of the wrap with a lot towards the last 1/4 or the wrap or even further back, depending on the cue length and player arm length of course.
In your situation I would find an instructor that can start you off on the basics and work with you to find a cue that you are comfortable playing with.
