Here's a list of great players and their cues. See any expensive ones in the list?
Johnny Archer - scorpion (but used a Schon for years)
Alex Pagulayan - Schon (with predator shaft)
Earl Strickland - Gulyassey (but won 3 world titles and 6 US Opens with a Cuetec)
Shane van Boening - Cuetec
Allison Fisher - Cuetec
Jim Rempe - Meucci
Stephen Hendry - John Parris (but used a PowerGlide one-piece for years)
Ronnie O'Sullivan - John Parris (worth about $800)
Archer-paid to play with Scorpion
Earl now plays with a Meucci and won 5 US Opens, not 6
Shane-paid to play with Cuetech
Allison-paid to play with Cuetech
Rempe-paid to play with Meucci and said years ago that if he were not, he would play with a Southwest
In my opinion, the custom cues you mention do hit better, as I said above, if I found a production that hit any where near any of my custom cues that I've owned over the years, I'd be playing with it.
