A somewhat different look at soft-hackles, spiders and flymphs. When these are wet and viewed as the fish see them you'll see better why the can be so very effective. As you look down through this post you will also see that most all freshwater fish will take these flies, and in a variety of waters, from still water lakes and ponds to small streams and large rivers. Using a couple of retrieves as well as just letting them roll with the flow you'll be very surprised how effective these simple flies can be.
Tie up a few, or pick some up at your local fly shop and give them a try.
