I found this route contrived - if you follow the exact line of the bolts it is probably much harder than 5.9. However if you stay 3' farther right near a corner it is a lot easier, maybe not even 5.9 (this avoids the big roof completely). Above the roof, move left to a 2 bolt anchor (one with missing hangar). Hubbel's guide shows this anchor as the end of the route, but somebody has added 2 more bolts and a top anchor to make an enjoyable finish.
The slab below the big roof is interesting, especially for N Table, where slab climbing is relatively absent. The route is longer than most at Table, so I found it to be pretty enjoyable.
Not a bad route if you stick to the slabby stuff climbing directly over the bolts and then pull the roof without bailing out right. If you stuck with staying to the right of the route all the way, I would probably say about 5.7 or 5.8.
