Sunny Day, high pressure (from anglers and mother nature) try the spicy crab.  Featured pattern in the Big Appetite Smallmouth DVD.  The next 4 months are prime smallmouth time.  Crabs other wise none as crayfish are not the big fly, sexy to tie patterns you read about they flat out catch fish. Plenty of open smallmouth dates open starting in July, once I get through the Hex cycle. Give me a call or shoot me an email.  July – September great months to chase the bronze back before muskie and steelhead seasons.
