Excellent link. Some of the best fishing down here in the south west is over rough ground, and the potential to lose a whole heap of tackle is phenominal. Rocky bottom setups, whichever ones you choose, are are a must if you don't want to have to look into a second mortgage to replace the amount of tackle you would otherwise lose!
I too would be interested in finding out how many different types of rocky bottoms anglers have invented. There must be absolutely loads. :)
