Hey Man, Nice blog! Love the pics too.
How do those black beauties and zebra midges do?
Where are they good at?
Hey, glad you like the blog.
The BB and ZM are good trailing under a dry fly on a dead drift. They simulate the broad category of midge, emerging midge, nymph... whatever. You can tie them in different color thread like olive, tan, and black depending on the food in a particular stream. They can also be pulled slowly through still water or just sat under an indicator for cruising fish. Even better when attached below a bigger nymph like a stone fly making a 3 fly rig.
