What kind of knot are you tying and what kind of line are you using? That accompanied with the correct weight of bait may assist you in losing less lures. There are better lines out there for abrasion resistance. Braid is great for strength but is easily cut on rocky bottoms. Learn a great knot and learn to tie it well. Always wet the line before you cinch it down as you might be burning your line and causing weakness. Just some ideas!!!
