Washington Hwy 20 then 155 to Grand Coulee Dam
This is the route I am planning to take in September from Fidalgo Island. Any problems with this route? Should have mentioned, staying in Omak while a friend visits relatives in Canada.

According to Google Maps, the route via 155 is just a bit shorter than the one via Pateros, and time is about the same.
You may need to set your departure date to a summer one, since WA20 is closed right now, and GM might not give you a route through Winthrop.
I haven't had a sense that 155 is any more remote (or dangerous, in what ever sense?) than 17. Overall the north route might stay a bit higher, but the south one drops lower, at the Bridgeport river crossing. I've even taken the Columbia River Road, which skirts Omak Lake and the north shore of the River downstream from the Dam.
But speaking of grades, you could switch the route means to bicycle and see a route profile.
