I obviously don't know squat about TR. With that said however here is a thought. It seems you all had a huge die off of shad this year; maybe the K's are not in their usual places due to this?
On our trip down earlier this year(first part of May) we caught about the same number of K's as we did smallies. Most all fish were caught between 5-20 feet of water with the K's coming on the deeper end.
