As a TD, you're always trying to balance player's pack with payout with extras.
In the end I think what keeps people coming back is that they find value in their entry fee. Value comes from something different for everybody, so I try to put on the best tournament with the best environment.
It will be best for everybody if one day "payout" goes away. This is something the PDGA should force on events. This would allow for TD's to focus on less things and allow a focus on bringing in more sponsors and events.
But, as a TD, i can't justifying changing to a trophy only event yet. There is a chance that turnout will be low as it's a "strange" thing to do. It's almost a death sentence to do trophy only at the moment.
