I have a Navigator 165CS with the F-90 and love it.
Small enough to play in most places, and wide and deep enough to handle the big water (on reasonable days).
Doubles as a waterski and tubing boat for the family
:-)
The church boards will serve the walleye application as well as doubling in a Musky role as you can adjust the weights and pull some of the smaller Musky baits (2-3 oz).
I am using a large Frabill Pro Formance net and am very happy with it.
I added an Opt-Tackle 'net clip' to keep the mesh under control while preparing to net the Chinnies.
