Unfortunatly, I do not have the luxery of using the good- factory backed aircraft cable and the good crosby clips- (not that I know the ones at the hardware store are bad because I honestly can't remmber if they are forged or not). I am going to be stuck with what ever the hardware store has- and I know they don't have the great aircraft cable- so what I am asking is if I am flying a light weight foam faced flat what size would you recomend when using the cheap stuff, and, what size would you recomend when flying a 4x 10 foot door flat? Please save the lectures on using the good stuff for another time. I don't have a choice- it is this or piano wire... Thanks.
