Id start with random draw doubles. $6 or whatever. If your part of a club or have a desire to improve the park/course, you could have a dollar ( or more. ) per player taken out. You could also have a CTP and/or ACE fund. If you are a member of a club or hosting on behalf of, you should charge non-members a dollar less, as they already paid in, so to speak. The rest goes to payout.
