I have a nice hitting cue.. Birdseye into ebony 4 pointer. I had an old shaft with a brass 5/16 joint I didn’t like so I plugged it and tapped it for a 3/8-10 screw. The shaft hits the best I’ve ever felt with a nice ping to it. I was finishing another shaft and tried it out on a different butt, it hit ok. So then I tried the same shaft on the ebony and Birdseye butt and wow hits the same as the other one ...sweet. I realized this was the butt making these shafts hit like this. Anyone else experience this? With so much focus on shafts, ferrule, tips, grain etc..... does anyone ever think the butt has a lot to do with how the cue hits? Any thoughts?
