Two Years
I started buying custom cues in 2004. Chudy, Capone, Hercek, Bluegrass, Sugartree, Morris, Howard, etc.
I would play with them until I got a new one then I would play with that for a while, from like 6-9 months. Two years ago, I saw a Tascarella Hoppe for sale and had to have it. It has a hit, sound (loud) and a feel that is perfect for me. I only have a few other cues now, but a few weeks ago I brought them all to the pool hall and played with all of them.
Still using the Tasc, can't put it down.
