Was doing a bit of casting in the weekend when I busted my braid on a cast. The break happened because of a small wind knot that only briefly tangled but then unraveled itself. However the braid snapped about 1m and a half form the joining knot and the braid, leader and lure went sailing away.

The braid was Daiwa Samurai 55lb. My question is is this normal to happen as I thought it was very weird because surely there was not more than 55lb of pull on the line as it tangled momentarily. Was there a fault in the braid? Or was it just angler error? Any ideas? Or should I just respool with a different braid? Would hate fort it to part while playing a fish in open water.

ok, just me then huh, got the jerk spice casting factor. Have to go test out Mrs Palmers and give her a quick shock. 

yeah that's worth considering as I was using a crimp to ring and I usually use a swivel.
