A lot of it is desire and the willingness to put up with the hassles of "being on tour"...guys like this will play in big sweeper tournaments - you also gotta realize that he OWNS the lanes he was doing this on, and although he's STILL a dynaminte bowler, it's the same for him to go somewhere as what you see for the pros on TV.
The MAIN reason you don't see many televised 300's are the heat generated from the lighting changes the lane conditions up to 4 times within the same game! And now, with the "stadium" format they're going to, the humidity from these outdoor/large-air stadium setups makes the ball react differently...WAY too many things.
You or I would be LUCKY to break 200 under the same conditions...in fact, you'll see some of the earlier rounds where guys are throwing 170's-180's.
I've been to Pete Webber Sr's alleys and house - these guys are as good as they are because they practice non-stop. It's JUST like a job to them...they practice 6-8 or more hours a day...in Webber's basement, he's got a 5 lane setup - guy had the whole area soundproofed because when he's got a hard time sleeping, he said he'd go throw a few games to relax and wind down, and he'd be out like a light!
His kid, though, was a first-class jag to me and the rest of the group I was with - to the extent that his dad made it a point to tell him to knock it off and leave...come back when his period was done. I've never had the same sense of satisfaction at seeing a parent discipline their kid (and rightly so). I also had a whole new respect for Sr as a person, as well as a bowler.
What is this "place" you speak of, or is that revealing a "trade secret" that might make it back to the rubes you sucker in?
