That's pretty much the route I would recommend.
Never done the section 10; I found a little niche in the wall across from Nike. If you cross Walker at Park Way and go through the residential part, the opening back onto Murrey is right there [it's a like a zig-zag through the wall]. It is easiest to find it from the Murrey side.
I won't speak for the intersections during commute hours though. Never done it.
