Best Silk for Whipping?

[Wyrda]

Hello,

I was wondering if anyone knew a good silk for whipping English livery arrows? One of the problems I have is the silk being very weak and often breaking during fletching or in use. I've tried Guttermann silk which is very weak, I've also tried another brand of silk which is 30 weight - about the same thickness of the Guttermann linen thread and is about as thick as I'd like to go - and while it's a bit stronger it's still very weak and nowhere near as strong as linen.

Ok well, not replies but I found a pretty good silk. I got some Japanese Daruma silk which is quite good, very fine at around 50 weight, about the same size as the Guttermann thread for easily separating of barbs, but it's a fair but stronger.
