I managed this fine chap last night whilst prospecting a deep pool with a skated sedge for trout
I've found beetles to be very succesfull also, especially when they're in a group and competitive, plopping a bucktail slow sinking beetle a yard or two infront of them normally induces greed as every one of them darts to intercept it!
Big pike flies will take big chub too, just make sure you use a wire trace if there are pike in your water.
Oh and wait till the 16th before you target them
Cheers,
Graham
