Hwy 1 is really nice but the traffic can tire you out if you got a long ride ahead of you.
There are a lot of roads that you can do but you said you are not looking for a 12 hour day so I would suggest 2 awesome long roads: Hwy 58 which you can do at a pretty good clip as far a backroads are concerned and Hwy 33 which is just spiritual.
You can slab 101 to 58 grab some food and get ready for the good part.
Hwy 33 will drop you around Ojai and if you are looking good on time you can make a route for the .

I was in Pasadena 2 weeks ago and psuedo slabbed up to Ojai, did Hwy 33. Stopped off at Jim's place off of Hwy 166 home of the
Rev Pack, then I ate in Maricopa... :barf i matyred myself already so nobody who reads this thread should have to. I didn't try all of the cuisine Maricopa had to offer but the other 2 places didn't look that great either!
Caught 58 to 101 then slabbled it home. All told it was about 9 hours with lunch and picture stops but I had the afterburners on from Salinas to around the San Jose airport where traffic got heavy.
