Just don't get stuck in a nonproductive pattern in cold water. On my favorite lake, I can usually find big smallies and get them to bite with one of a couple of presentations (jigging spoon, small jig). They are usually in specific areas, at specific depths, and can be bunched up. Last Novemeber, I took a couple of other yak fishers to the lake, told them about the pattern, then proceeded to wash lures for the next 1.5 hours. Out of frustration, I tied on a preacher jig and headed into the shallows to look for pike, just to make the rod bend and warm myself up. Bam! Smallie in 3 FOW. The next 45 minutes was some of the best action I had all year, with all the bass hitting softly but consistently in 3-5 FOW, well away from the nearest drop off. Water temp: 52 F.
