Greg, I'm having a hard time expressing what I'm trying to say here... I've deleted 4 different versions of this post, so I'll just say it kinda straight.
I shoot on bar boxes because that's what's in most places. When I go play a tournament, such as the Derby, I'm going to be playing on 9' tables with 860 cloth. I want to practice on the same cloth as I'm going to be playing on when that tournament comes around, otherwise my speed is going to be all screwed up. What this sounds like is just another way for Diamond and Simonis to tell people "YOU NEED THIS" even though they don't.
For years I shot on Championship cloth. Then everyone was saying "Oh, that's so SLOW! Simonis 860 is where it's at!" Now, the person that designed Simonis 860 is telling me that 860 is too fast for a bar box, so I should support this new cloth.
Tell me... Why would I want to shoot on 960 over 860, when 860 is the "gold standard"? You said yourself that you helped design 860 because 760 was too fast, and now you're saying that a 7' table should play slower than a 9' table. Are you going to come out with a 910 for the 8' tables next? Are you going to put 760 on the Bigfoot because it should play faster than a 9'? Or will 760 not be fast enough, so we have to go to 660 on a 10 foot?
I guess what I'm asking is, why do you think that a 7' table should play slower than a 9' table? Shouldn't it be the idea to get them all to play as close to identical as possible?
