I think this is a great thing you are doing for pool and I would like to make a suggestion that I think might be interesting.
I think the winner of this match should be crowned the US money champion(as these gentlemen were the first to step up they should have an advantage) and any one who wants to step up and challenge the champ should have to go through the #2 guy first (loser of the initial match), say $10,000 to play the #2 with the winner to play the champion for $15,000.
As people challenge they become a rung on the ladder win or lose and people have to climb over them to get to the champ. If you could manage to fight your way up the ladder over say ten people with a starting match of $2,500 and the next match worth $3,750, then $5,625, then $8,437, then $12,655, then $18,982, then $28,473, then $42,709, then $64,063, then the finals against the champion would be for $96,094(all numbers aproximates I did not round or include decimals).
The players fighting their way up get to keep half of their winnings from each match and half go into challengeing the next person up the ladder, the challenger would have made almost $94,000 by the time he reaches the final match with the champion for a $2,500 investment. If the bottom rung always stays at $2,500 imagine if their were 20, 30, or 40, people what the championship pay out would look like, also anybody on the ladder could challenge the person ahead of them to attempt to move up and any one who doesn't play a challenge match within a six month period forfeits their spot and goes to the bottom of the list.
Just my thoughts, keep up the great work!
