Don't know how DD got on but I was out all day on all three tanks and it was tough. I wound up with two on DB's, after dropping two, but only after moving to number 3 in the afternoon to escape the gusty wind. Stepping down to 3X might also have helped though. The tanks are full but clear.
One old chap who fishes Chew had bagged up on his first visit, at Ivy Bank, using a booby and Di7 but, more encouragingly, a chap by the water-treatment outlet, popular spot, others were catching, took six on small black buzzers, [ the only, sporadic, hatch of the day.]
Young Ashley had four when I spoke with him, with two on nymphs and two on the mouse. Another regular was packing up with four for the day, but again, all from no. 3.
Fish were showing late on by the trees but, try as I might, I coudn't get decent turnover at the range required with a dry.

Good fun trying though.
