In Northern California we are blessed with a spring steelhead run and some tailwaters with large rainbow trout match this with some of the biggest caddis hatches of the year in the spring and early summer and you have a great situation that shakes out to swing flies on trout spey and light switch rods. While most Trout Caddis patterns out there work just fine for this type of fishing they are not ideal for swinging and holding on to bigger trout and steelhead. So I started messing around with tying my caddis patterns on bonefish hooks. I figured bonefish hooks are built to tie small bodied flies and hold on to bigger hard fighting fish. So after many variations and small tweaks I came up with a pretty simple traditional caddis soft hackle build for swinging.
