RE: 3D flying
Well Denis why not put your theory to the test and promote your event as a NO 3D event and see what kind of turnout you get.
This whole argument seems to be an old school vs. new school debate where some want things the way they used to be. With changing technology the hobby is moving forward and new flying styles have emerged that attract younger flyers. Flying fields and events need to change with the times if they want to keep a majority of pilots happy. Of course there will always be some that can't be pleased no matter what.
