In the past, line size has helped a lot.
In AMA Fast, we used to use .014 solid or .015 stranded. With the advent of SuperTigres, we were losing planes like crazy. Most guys voluntarily went to .018" stranded before AMA made it official. In addition to more stell in the cross section, the .018's help slow the planes down, reducing both confusion and kinetic energy.
F2d was flown on anything to .011". After countless flyaways, they went to .015". Remember the Nashville TT of ought-83? One competator, who is known for his combat column, tried to make the team as the last man using .012's". He lost at least one, if not to toys per match.
An upgrade in line size has worked at least twice before, and it might work again, if the go-fast boys would give it a chance.
