JT:
I would have to agree with "banged up" -- although yes, there would be less clustering on a 10-footer due to the balls having more horizontal real estate to move around, the distances involved are much greater. When moving from a 7-footer, to an 8-footer, to a 9-footer, to finally, a 10-footer, the slate real estate increases exponentially, and so do the shot distances.
I shot a couple times on an old Brunswick 10-footer that a friend had in Norfolk, VA (where I was stationed in the U.S. Navy in the mid-1980s). This old Brunswick even had cigarette ashtrays built-in to the "steel catcher's mitt" outside the corner pockets (they were molded-in right from the factory). I gotta tell ya, even though I'd been "raised" on a 9-footer, that 10-footer threw me for a loop for a while, until I bore-down and focused on my fundamentals and aiming. It was not unlike the "shock" I experienced when I shot on a snooker table for the first time.
I can definitely see why Earl Strickland is a staunch advocate of "weeding out the real pros" (his phraseology) by having them play on a 10-footer, like he supposedly owns. Me personally, I would *LOVE* to own one of those old Brunswick 10-footers with the nostalgic cigarette ashtray cut-outs in the corner pockets' steel catcher's mitt. I'd have to completely clean out my garage for it, but hey, ya gotta do what ya gotta do for a prize like this!

P.S.: I'm seeing more and more threads by you asking first about the differences between a barbox and an 8-footer, then the differences between an 8-footer and a 9-footer, and now this one -- asking about the differences between a 9-footer and a 10-footer. Could our barbox Johnny be thinking about stretching his wings into ever larger tables?

(J/K, of course.)
