Well as long as Magnumsk mentioned it and posted the link, here's my story. A few months ago I asked here if anyone had a report on the McDermott/Star Go cue. My real passion is motorcycle touring and my hobby is pool. I was interested in this 3 piece cue to fit in my saddlebags or tour-pac.
At $150 it was the cheapest farkle for my bike so I bought one. I ordered a 19oz. cue. It felt very heavy and in fact weighted 21 plus. I pull out the bolt and took a hacksaw and file to it and it's now 18.8. The bolt is a very tight fit, BTW.
Now I know there's a thread here about "do L/D shafts create more spin" Well this has a sold maple shaft 21" long. I don't know why but this Go Cue gives me more draw than any cue I have ever shot with. I use all solid shafts at 13mm, yet when practicing for say 12" draw, the ball comes back 2 or 3 feet.
As I said I'm a hobby player and no talented judge of cues. So I have no explanation as to why, but that's my story and I'm sticking to it.
BTW it will fit in the standard Harley bags or Tour Pac, the front trunk of a Can Am and the bag it comes with hangs off the Vespa bag hook on the leg shield. For car or airline travel it can fit in any suitcase or duffle.
