I was almost certain those I saw doing that were just trying to be sneaky-sneaky not flaunting their catch! We did have low-vis green line and one experienced fellow suggested running at least a leader of clear line. Seeing how visibility was probably 8-10' I suppose all of those also could help catch rate. Guess I will have to go again!!!! Oh but retying knots in the cold is not fun, ha. Thanks again. John
