I bought some flies from the Orvis shop in Jackson last week. Here's my take on them. One fly, came apart after 2 fish. Another fly had the hook break off on a fish. Never had that problem with any other fly.

One thing i always suggest if you buy commercially tied flies. Check the knot and add a dab of cement to make sure it won't come loose. Flies from Flyshack always come apart just from casting, unless I dab the knot with a bit of cement.
