so instead of that shrink wrap for the boom of my k110 I have been using that black cloth electrical tape ,it's really good as it molds to boom and stick well ,not any heavier than shrink (0.2-0.3 g)
but came across some orange braided cable stuff feels kinds sturdy and again under 0.3 g .
looks a bit like fishnets ... mmm kinky boom
adds a bit more weight as forgot about the shrink at either end to keep it on ... ahh I'll give it a whirl
