Dont be too worried about lack of flat ones right now. They are a bit quiet and that is to be expected around this time of year. Mid September they should begin to pick up and by the classic it will be firing. I have far more success on soft plastics from a Yak than trolling. I get the majority of my flattys in less than half a metre of water (last 2 good fish were 85cm and 81cm and water was 40cm deep). That is the advantage of the yak.
I am trying the classic for the first time this year (in a tinny). Good luck with it!!
