Black star climb is doable on roadie tires for sure, just watch your lines coming down. You will have to stay seated allot of the climb because of traction, so be prepared for it.
You could also stay on the lower parts of Aliso Wood but might bore you cuz it's pretty short. If strong enough, climb Cholla to the fire road on the ridge, take that to "top of the world park" then drop into Laguna via paved roads. Cholla will be a SOB with that gearing and limit traction, there is a easier way up the back side but never done it so I don't have details either will be a short hike if needed. Once up on the ridgeline, don't even think about coming down any of those singletrack fingers. None of it is smooth, it's very dippy and hard limestone, you will likely bend your rim or fork. Stick to the fire road til the top, take some pics of the islands and epic views of the ocean while up there.
