Whether you like the "hanging" or not, Carrier is a very challenging event. I almost got into carrier some time ago, but decided that to be good at it would take away from my big love of stunt. Nostalgia and .15 carrier are both interesting.
I hope that Carrier will again attract people.
I just completed work for Bill Bischoff and have developed laser cut ribs and spars for both his profile and full bodied Zero. I am sure that you will hear more about this from Bill, very soon.
Another event that used to have heavy participation is Scale. Hopefully,events like Uncle Mikey's multi engine 1/2A scale will stir up more interest there also.
All of this will help controline survive.
