I love using Beadchain eyes. Sometimes on the larger eyes the holes can have a sharp tag of metal that will cut your tippet. Be sure to check before you tie on the fly. A quick zap with a hook file or stone will slove the problem.

I don't paint or fill in my bead chain. If I want a heavier fly, I use hourglass eyes instead.

I'm not sayin', I'm just sayin'
