1/2A Scale competition models flown at the 2018 NW Regional Championships

It would seem logical that due to it being a 1/2A scale contest, any displacement larger than .050 would disqualify it. I would also think that .012 stainless would be the suitable lines. There's little weight and drag resistance penalty between .008's and .012's. .008 stainless lines are a real pain in the rear to maintain, they're very susceptible to damage and kinking. Scale planes typically don't perform like stunters or combat planes therefore .008's could be used without fear of failing, it's just that they're fragility makes them a chore. The use of Spectra while approved for combat, is always a debatable subject. Many CD's will deny their use because no one wants to assume responsibility.
