I would like to nominate Chris Waugh. Thank you for considering me but I will not be able to go this year. (no time or $$$$)
I also think you should consider having people earn their way to a "performance based" (i.e. handicap or rating) tournament by qualifying using performance based criteria. The person who has the best shot at winning the Performance Based half of the USDGC is a person who is steadily improving and has only met the minimum criteria (12 rated rounds). It is the nature of a rating based tournament that the player with the least accurate rating will win. Look at last years winner. He had the minimum rated rounds in qualifying and averaged 50+ points above his rating. I would love to think that i could maintain that kind of shooting for a whole weekend but it is not realistic. I think the person who should go is the person who has the best shot to win. IMHO
I understand your reasoning behind your selections. But, I think if more people had a shot at qualifying it would be a lot more exciting. Just my 2 pennies.
I'm sure you have seen this but more people should read up.
