After 50+ years of playing I've probably played 50% on BB, 35% on a 9-foot (probably 75% of that was 14.1), and 15% 3-cushion billiards. I am about an "B' player on a BB now and a "C+" player on a 9-footer. Use to be "B+" to "-A" on BB, and "B" on a 9-footer.
I have always found 8-ball on a bar box harder than on a 9-footer and 9-ball harder on a 9-footer than a BB. On a BB playing 9-ball, the hardest part is having a shot on the lowest ball after the break and getting position for the next ball. After that it's mostly a cake walk for "C+" and up. On a 9-footer the first two balls are as critical as on a BB, but then you have 8' to 9' going back and forth on the table. As far as scratching more on a BB...figure that into your shot % before you go 3 rails. If it's close to a scratch, find another way to get there or leave a longer shot. How long can it be???....less than 7-foot pfft...no problem.
On a 9-foot you need better position IMO, and be a better shotmaker. Johnnyt
