Looking for feedback on a promotion I’m starting.

Hey I’m trying to start my own grappling tournament and wanted to ask you all some questions.

1. Would you compete in an open tournament that offfers payout for expert division 
   

2. What format would you like to see (round robin, single or double elimination)
   

3. Would payouts dependent on bracket sizes be reasonable?
   

4. What rule sets would you like to be used for gi and no gi divisions?
5. Any feedback that frustrates you the most about other tournaments? I will have a venue booked next in December/January and have the Smoothcomp link up shortly after. If you guys could also give me a follow on ig @verusgrappling would be amazing.
