These flies are all great for sure, but the biggest factor to me is the line you are going to use. If I'm chasing walleye, lake or river, I always switch to my sinking line. And always out fish my buddy who decides not to bring his sinking line and just use weighted flies or weights on the line. He never learns...
Sure you will catch them but that guy using the sinking line will out fish you 2 to 1, easily, due to the more natural presentation it provides....and hugging just above the bottom made easier as well.
I've never fished the AthB for walleye but I imagine that river being one of the better ones for some sizable wallies.
Good luck!
