Last year in my 1st tourny of the year (water temp - 46 degrees), I caught a largemouth in 18' of water on a shad colored tube rigged with the standard internally weighted tube jig (I'm thinking 1/4 oz). All I did was cast it out, let it fall to various depths, and s-l-o-w-l-y swam it back in. I always think of smallmouths when I think of tubes. Ironically, all the smallmouth I caught that day were on a jerkbait. The only largie was on the tube.
Anyhow... do any of you have any experience with fishing tubes in mid-40 degree water temp? If so, what's your method? I was only able to catch that one fish on this method, and couldn't get bit again on that day, or other days I tried it. Obviously a tube will work, but apparently I'm missing something.
Got any tips?
