I'm sorry I didn't see your PM earlier. I'm a newb on this forum, and I'm not getting email alerts when I have notifications--certainly because of something I've setup incorrectly.
The Arnot balance point feels to me like it is a little more than a fist width down from the top of the wrap. I can't confirm or measure right now, unfortunately, because I'm on a plane to Seattle. I will not be back home until later in the week.
The butt and shaft do roll without wobble, and I do not detect any warp in the shaft during play.
If you'd like to check it out, we can certainly arrange that with a bill of sale entitling you to return the cue for a refund of the purchase price.
