Well tied flies. I fished them on the Boise river in town ( a tailwater ) for two days on a soft hackle set up without any hookups. I think that the size is large at 14. I fish other soft hackle flies at 18 and 16. I was catching trout on caddis nymphs ( Walt"s worm in 18 and 16 ) on my drop shot nymphing rod.
