For Coho the 8 wt will work, there are two other species of salmon up there
that would get my attention more rod wise. That said the fish overlap in the
rivers so I'd usually carry my Dan Craft 10 wt as the primary and an 8 wt
as the back up. I never go to Alaska or any where else without a travel
spinning rod for when the winds kick the bug slingers off the water. Been to
many places where the weather would have stopped my fishing otherwise. Just
happened again on the upper reaches of the north Bristol Bay drainages in
May/early June.
