Jon S, has already made over 400, others have as well, one i read even made it just past 500 in Europe somewhere?
On an 8' table with 5" pockets, i think some could do it now, if they really desired to and worked at it daily, most including John don't. Still keep in mind that at home on his practice table which he shot on every day for 8 hrs, he had runs of over 800.... so just beating the 526 is a start, not the end.
Though i would hate to see The Mosc old record finally beat, i would not really be impressed with anyone till they can shoot even 150 consistently as Willie did. Right now my money is on both Jon and Miko to be the ones to do so, but there are other contenders that may make it first.
Believe me, if i could racehorse the money to attract the best to do so i would, i am old so it would be my pleasure to see such before i pass on.

, even though it would be heart-breaking in another sense.
Lastly, keep in mind that as interviewed on the reason he only went to 526, willie responded i just got tired, as others, who stopped because they missed a shot, willie never did, who knows how far he may have went that day had it not been the case? something to think about huh?
