FA,
To be honest, I've not found the browns on the Clearfork to be real particular. In addition to the flies you have mentioned, take some bwo's, klinkhamers (usually the first fly I try there), adams, & terrestrials in sizes 12 to 18. When I first went, a friend told me not to bother with dries, but I have had them rise to take dries into November. Find 'em & you'll catch 'em.
I fish either my 2wt or 3wt with 6X tippet. Last year, Wirebender & I each got into browns around 15"...Keith landed his, I lost mine after a nice fight on the 2wt. Like other fish, they relate to "edges"....that is drops, grass & current edges, current breaks around rocks, & eddies off the current. Don't overlook mid-stream deep cuts & shaded banks either.
PM me & I'll put you onto a very nice spot on the Clearfork.
Mike
