I bowled in this event last year, and I'll say it was a great time. There only ended up being I think 42 entries, but it was still one of the best tournaments I've bowled in. It was run very professionally, and the tournament directors were very dedicated to making sure everyone was taken care of.
The format is great, 18 games of qualifying on 3 different sport patterns, then matchplay the rest of the way.
BTW, last year, even with only 42 entries, they still paid out around $1,250 for first I believe, and there was a ton of bracket action.
If you can make it, go. It's definitely worth the trip.
