On my last trip out, I had two instances of a uni-knot snapping at the knot itself. I've never had this happen before. On the first occasion, I simply accepted it as an abberation but when it happened twice, I changed the leader I was using. You could tell it broke at the knot twice. I'm not sure whether I did anything wrong - it was a standard four turn uni-knot which I wet before I pulled it tight. I pull the knots tight quite gently at first before really pulling it tight when all the loops have settled into place. Any ideas or suggestions?

Leader was Fisherman Stealth leader which I haven't used before for jigging. It stretches more than any other leader material I know and I like using it for twisted leaders for this reason.
