Highliner,

I had a Duckworth with a 9 or 10 degree bottom and it worked just fine for side drifting. Having ran Predators in AK on the Kenai, I like the way they track better when back trolling also than my Duck. I've been in Alumn's also and still like the Willie the best.

You will appreciate a little more deadrise when you need to run up the Columbia down at the mouth of the Cowlitz and theres a little chop.

All the boats listed above are definitely well put together and time tested (except the Thor, I don't know anything about them).
