You cannot shoot a rifle with any accuracy with out a sight, you can't just aim down the barrel like you do a shotgun, and you must aim down the middle of the barrel. You need a sight to find the exact center of that barrel.
It's the same with a cue shaft; you are aiming a shotgun, never finding the exact center of your shaft. You do not have a clue where the center of your ferrule really is.
If you want rifle accuracy then add a sight, so the same with a billiard cue. Get a broad felt tip black marker and paint the edge of your tip black, it shows up much better than the brown dull of your leather. Get a sharpie red felt tip pen which has a thinner point, like a flair pen, and run a red line from the bottom of the tip across the ferrule to the bottom of the ferrule where the wood begins.
It is important to make this line straight, so lay your cue down inside a long rail with the tip up on the pocket, and lay a ruler along the shaft so you can draw the line parallel with the center of the shaft. I demonstrate how to do this on the new DVD on how to shoot trick shots. Draw the line from the bottom edge of the tip to the top edge of the ferrule.
Hold the ruler firm so its outer edge lines up in the middle of the shaft and the line will then draw straight. Use a red or black sharpie, it makes a thick line and the ink does not run.
On my Meucci shafts I have had the red dot put 5" below the ferrule instead of down by the joint which I think is a dumb place to put it, so my ferrule red line is in line with it. Buddy Hall has his red dots made the same way. The red line if it went far enough would divide the cue in half.
Standing up when I am seeing and visualizing the shot, I have my bridge, my hold, and I look to insure the red line is up. When I get ready to drop on the shot every thing is in place and ready to shoot.
When I plant my hand I try to have that red line up, or I then twirl the cue so the red line is now on top of the shaft. That insures the red dot is also up. I now aim that line into the cue ball. This makes me have a tighter focus and aim and my accuracy of my shots becomes now much higher. I now do not have to look down my shaft to find this tiny red dot which is hard to see in a dark pool room. I never want to look down and away from my cue ball; I want my focus on this.
If you don't like the line, you can always just sand it off. This concept is not for everyone. It works for some, for others it does not.
Every shaft has a pure spot, where the grain aligns and shooting with that proper spot will give you the least deflection. That is the purpose of the red dot; they measure their shafts, find that spot and mark it. That concept has been known for over a century.
Snooker cues always came with half of the butt sawed off flat so you would know where to place your hand and that flat area. Pool and billiard cues at the turn of the century had the same thing. The purpose was to have the same part of the shaft up every time. They did it by looking at the grain. Even if you mark you shaft any place and don't even find the right spot.
The cue will still play better because you are hitting the same place every time and the deflection now is the same every time and won't vary on you as it will when you rotate the shaft on every shot hitting in a different place.
Does this sound crazy to you, probably, but Luther Lassiter did that on his ferrule making it red 45 years ago and became the greatest 9 ball player of all time. Nobody had a clue what he was doing or what he was up to. He dominated pool and Johnston City during the 60's.
