I noticed a prolific hatch of size 16 grey more than brown stones on my local river over the weekend. Waders and vehicle were covered. Tried to match the nymphs with size 14 hare's ear and PT without success. Did c&r a couple cutts on my go to bugger. First, is the rule of the nymph being one size larger than the dry true for all insects? Is this a hatch worth matching? I saw no surface activity. Any suggestion on flies, wet or dry?
