I vote for combining with Classic Pattern.  I'm not brave enough to turn my back to the flight line while a Scale guy is flying . . . .

I'll get back up on my soapbox about turnaround in the lower classes - it makes pattern too complicated for the average club flyer.  I get lots of questions about pattern at my field since I "mix it up" with everyone during regular flying, but their eyes glaze over when I explain how the turnaround maneuvers work.

I think that the CPA rules could be used to start something along the lines of a "Simplified Pattern Association" or "Regular Dude's Pattern Association".  No stinkin' aircraft limitations, guys fly what they have.  No turnaround.  No making the patterns more and more complicated every year.

How about coming up with a contest format that you can do while sharing the sky with your club's open flying - i.e. run one flight line but allow the contestant to work his takeoff and landing with the local traffic.  Yes, this would need an "avoidance" rule.  That way you could have a contest every Saturday at your club among a group of local guys.  At first you'd attract 5-6 guys, but since you're working your contest flying in with the open club flying you'd eventually have a couple "walk-ups" who would want to give it a try for a round or two.  Of course you wouldn't have trophies for your weekend contests, but simply keep score amongst yourselves and announce the winners in the afternoon when you're done.
