a long string of 8/9 ball wins or a semi-decent straight pool run. my straight pool run usually maxes out at 10-12 against other people because i don't care, i'm hoping to get it to 50+ by myself with other people watching.
40 years ago the pros had 14.1 high runs that most current pros could only hope to achieve. The fact is that 9-ball is the game today. Given that, perhaps right now it migh be more impressive if someone posts a 400 (+) run in straight pool. It seems all the top pros have strung together 8+ racks at one time or another, playing 9-ball. But how many have run 300+? Very few I'd imagine.
