One happy development: I've learned to make knots that are so strong they're actually stronger than the lures I use. Twice I've got (cheap) lures caught on submersed branches. Using gloves and brute strength, I pulled on (itself immensely strong) braided line I'm using and managed in one case to tow the branch (or whatever I was hooked on). Doing so dislodged the thing from the lake bed to the point that a big gas bubble came up. When the thing suddenly snapped, it turned out that it was the lure that broke, not the knot failing.
The knots I use: trilene for mono and fluoro lines; surgeon's knots for putting together unlike types of line; and the mighty palomar for braided line.
