Hi,
thickest size for main rigging, medium for control cables. I think it looks very good - used it on the Roland C.II. Thinnest is OK for 1/72 aerial cable etc. I used black but it will take painting with a metallic (steel) colour.
Cheers,
Graham
Duh! I was thinking about the UVR line. The thinner of the two EZ line sizes is OK-ish for 1/32 rigging but it will de-strand for a better effect (you can select the size you want - it can be fairly consistent).
