Bass Forage and swimbait size
So I've been fishing what I would consider big swimbaits for about 2+ years and haven't had much luck on anything over 8" in size. This has me thinking about the forage in my lake. The bass in my lake mostly eat threadfin shad, there are some gizzard shad but not a huge population. There are some bluegill too and crappie, but I haven't had much luck on lures that imitate either of those two fish. The other side of it is that the bass in my lake don't grow to giant size. I rarely hear of anybody catching one over 5. Should I stick to the 6" baits and smaller or commit to throwing out some big baits?
Also just as a side note, my lake has very little cover near the bank. Its almost all rock and dirt. What little cover there is can be found at the back of coves and that hasn't produced many fish for me. Thanks for the help!
