I'm not a huge fan of the unlimited qualifying but at the burn rate of balls, I doubt WGT would ever give it up. My suggestion would be unlimited but no restarts. You have to finish a round if you start or you are disqualified. That would end the play the first 5 holes till you get 5 under par method and make players put in more to qualify.
I would also like to see a little large qualifying field, maybe 10 strokes of thed or the first 300 players. Only play the credits to the top 100 and ties after cutting after round two.
I think the same players would win but it would make it more interesting.
