Neil...
"Actually", You're wrong. The guy wouldn't need one, he would need two. I very specifically said in that post that "I think the scratch/scratch and then pushing the cue out to a straight shot on the four". But you should know that, you quoted me saying it.
And no, the one rail and the 6 rail don't offer the same results, because one-rail lagging to that safe-zone = you have no shot of hitting those balls unless you do by complete accident. With the 6-railer you are trying to hit the 8, and if you miss you're safe.
So you mean to tell me that when a player sets up a game he will hands down play on ANY table without having any idea how it plays? He's not even going to bank the cue around and lag it to see if it has any dead-rails or funny rolls?... wow, I must be stupid for doing that before I play someone on a table I'm not used to - why take away the surprise?
Seriously though, not testing out the table a bit before playing for something of value, that would be really stupid, I don't care who does it... for all you know you're walking into a huge gaffer game.
The shot isn't MY shot, it's a shot someone showed me. I thought he was crazy when he showed it to me, but then I tried it.
