Edit: saw Hell's and AJ's comments. good advice. Route 4 really isn't so much challenging as long. Route 5 North is pretty easy except if your like me and you dump your bike in the Malhuer. It's the souther half of 5 that is killer.
I'm still open to suggestions. We have some time to iron out route details... Route 3 looks stunning too! And looks like there is some truly stunning scenery! I don't think most of us could do a down and back of the whole thing though, so there would still have to be a customized version for this trip.
Thanks for the tips!
