Good effort Brett. Sounds like a great trip.
I have got all my large togas out of the main basin area. Yabba can be good, but I have now caught and seen caught just as many from Kingham. My last trip saw some absolute horse togas in a few of the shallow bays up Kingham but I couldn't get fly to them. Probably should have taken to foot and stalked them landbased/wading.
