My issue when I ran my original optima Ina couple of vintage heats a year or so ago was that there were a few re re rc10s with unlimited spares, going like the clappers and one took out one of my front wishbones. I was running a 17.5 to keep speed sensible.
I don't object to re re at all, and now have the re re optima so I can shelf my original, but when you have a mixed heat it can put the old ones at risk.
Mind you, so does my driving
