Tim we inspect our aircraft every 24hours. Its called a pre-through or post flight inspection. We also have the calendar or hourly inspections. FUN TIMES!
And I am on the same boat as PTP. I have synth trap lines and I have to pay close attention to them now. I inspect them very thoroughly after every race. I have to replace a few lines myself. So it is good to inspect everything before and after each race day. If you think something can fail it will. Just replace it and avoid worrying or thinking about it out on the water.
