I'm not about to name them. These are people I know. I'm not saying you don't have to come up with shots. I have more respect for straight pool than that. I'm simply saying that straight pool players don't spin the ball around the table as much as nine-ball players do.
It's been three years since I left NYC, so I'm not sure who the new 100 ball runners are that have appeared since I left. But of those I knew, in no particular order--Flocko, Ginky, Mika, Vinnie, Tony R, and the late Johnny E and George Makula--all are/were outstanding 9-ball players. You don't run 100's if you can't make long shots or maneuver the cueball. Any legitimate 100 ball runner in straight pool can do pretty much whatever is necessary with the cueball--long, short or in between.
With regard to slip stroking, the aforementioned Johnny Ervolino had the prettiest slip stroke I've ever seen. He could also control the cueball on impossibly fast tables as well as anyone. I believe he told me as a kid he copied Mosconi, who was also pretty fair at controlling the cueball.
The idea of throwing the cue or slide stroking is nothing new either. I don't really know of any top player who actually lets it slip forward pre-impact, but plenty let it go post impact.
What is really important, and well advised, is releasing
pressure on the cue just prior to impact. Watch any top players and you will hear the cue resonate at impact. This is because they soften their grip just before the cue makes contact with the ball. Many players who appear to have a firm grip on the cue--Allison, Sigel, Rempe and Miz come to mind--release in this way. You can't always see their hand release, but you can hear it.
A cue that is clutched tightly at impact does not resonate. Releasing pressure in that way allows the cue to be released without the interference of muscle tension, resulting in more accurate and consistent delivery.
