We did the "Shuttle" option!  Did the usual route to the lake but mixed it up on the way back. 

Here is a quick map of the route we took from the lake to exit 42. It is a very straight forward ride with no real chance to get lost. From the T (orange line) where you normally go right to go back to the Hansen Ridge trailhead you stay left and follow the road. It is crazy steep for a bit then mellows out. I had it at 4.6 miles from the "T" to the start of McClellan Butte trail.
