I'm also surprised at the people that don't use a shock leader, or don't know why it's necessary, or don't know the correct length, which for anyone that doesn't know, is 2+ rod lengths, a bit for the drop, a rod length and a few turns on the spool, it's no use using a shockleader if the knot is half way up the rod, it'll always snap off at the knot.
Also, kinda related, is pulling for breaks when snagged, keep the rod tip low and preferably under water, wrap a couple of turns of line round your forearm and walk backwards, lots of people just heave and heave on the rod, worst case scenario is what happened to a carp angler a few years back doing that, the rig became unsnagged at full pull, the lead hit him in the face and was embedded, fully, in the back of his eye socket, that was a 3oz lead.
AL ..
P.S. for Pagham Pirate, I personally wasn't referring to using a shockleader for spinners, that'd be daft or when using 3oz leads on 20lb line, just to be clear, I was referring to Beachcasting, with heavy leads.
