I see fish hitting the surface early and late at PK. I usually don't chase topwater. Kinda like playing keep away. By the time I get to where they are hitting, they are now hitting where I came from.
Best fishing I have done has been at night around green lights. Catching mostly under 20 inch stripers with most of them throwbacks and an occasional LM bass. I have not seen any sand bass on the lower end of the lake in a while. If I were you, I would call Randy Wood or one of those other guides and see if they would give you a tip on where sandies might be. Sure worth a try.
PK is fishing tough right now. There's more bait than even last year. Every cove and creek is chock full of shad. I got skunked with live shad fishing on top of a huge school of stripers. Hard to believe you cant get stripers to bite but they are sitting in a fog of bait.
Good luck to you.
