I'm looking for a good still water adult stone fly pattern, which is not to difficult to tie. We don't get many stone flies here in Australia, lately the lake I have been fishing has hatches of stone flies quiet regularly. They are quite small size 16-18 (some a lot larger but not many) and they are dark Grey in color. The parachute Adams is sometimes doing the trick on a few fish but refusals are more frequent. Thanks in advance,


Darren
