Just posing an idea here... let's have some views.
We're all familiar with the 'ladder' format of competition right? How about a completely non-STACK-sanctioned (unless they want to) Trick Out ladder format?
All the interested parties start on a ladder, in whatever order is deemed applicable. You may challenge to a Trick Out any competitor above you on the ladder. At the next sensible opportunity you fly against that person following the standard Trick Out rules - music, six alternating 30 second rounds, judged by your peers. Maybe in the arena, or an appropriate clear area of the field, at a fly-in, whatever.
If you win, you swap places with them in the ladder, or move above them, or however these things work (spot who never played organised sport before ).
Some of the finer details would need to be thrashed out obviously, but what do people think of this idea?
