Question for the Stakehorses/Match-up Artists?

I am arranging a few games here locally, and I wonder what is the most fair split.

First, the payout should be over $10,000 total. Second, the fish cannot win. Third, the bet must be high to start.

I offer some options in the poll for a fair monetary division, and would like input for any other fair options. Or input as to what of my options are unfair. All opinions greatly appreciated.
