There's good and bad to all the suggestions made. I think you have to look at the truths inherent in the tournament and then make your decisions accordingly:
1) The number of people capable of winning this event is a mere fraction of the total number of entries, but the prize fund is funded by Joe Bowler and Friends,
2) Given that amateurs are the target of this tournament, you have to make it attractive to bowlers of their ability level.
In other words, true high-average guys who take the attitude of "so what if you can't win -- practice and get better" are just making noise, to me. The true national championship for those guys is the U.S. Open. Golf has its U.S. Open for pros and pro-level people, and the U.S. Amateur for guys of lesser ability but who are still talented golfers.
I don't understand why this tournament isn't handicap-adjusted, unless the USBC knows that sandbagging is so much a problem that the entire system is flawed. And if that's the case, why do they advocate the system -- at 100 percent, no less -- for their leagues? It's a mixed message.
I also don't understand barring USBC-legal cleaners at the Nationals. I'm sorry, but that's just stupid. Stupid.
If you want to win big prize funds and call yourself the sport's real national champion, the U.S. Open is where you need to go. If you want to win Eagles and call yourself the best amateur bowler of your skill level, go to Nats. So I wouldn't have a problem with adding other divisions.
However, if you're going to do away with the Classified division, then anyone who has or has ever held a PBA card should be ineligible, and steered toward the U.S. Open instead. Right now, those guys are having their cake and eating it too, at the expense of the amateur.
