Yes,, there's a rule..
The single most important rule in harnesses...
It has to be long enough..
It shouldn't be taking a shock load..
If it is there is something fundamentally wrong with your set up,,
( either to short of a harness or too energetic of a separation charge )...
As long as the harness is long enough,,
it doesn't have to be killer strong at all....
So is my harness strong enough isn't just a function of the weight of the rocket and the strength of the harness,,
it's also very much how long is the harness....
Every mill measures physical size and weight rating differently..
I've seen 1/4" a bit bigger then my 1/8" super small light Tubular Kevlar,,
and I've seen 1/4" really big heavy strong material...
I'm pretty sure if I remember correctly that Tim L's was really strong heavy stuff...
Make sure it's long enough,, no probs at all...
