Have posted this in freshwater section to.
I have been asked to replace a broken snake guide on a Sage 6 weight fly rod for someone. Only ever done a couple of these over the years but nothing as delicate, can anyone tell me what size thread one should use as I don't want to upset the balance or action of the rod, guide is 2nd on down from tip.
I was thinking of using some 1kg mono or as below in photo also thinking flexicoat maybe bit heavy so would fly tying cement be more suitable to coating binding.
