Long and moderate, Tis-Sa-Ack is the route most often climbed after the Regular Route and The Direct on Half Dome. The cruxes are a few thin placements, but generally the route is straightforward and cruiser. Tissack is technically easier, but about as overall difficult is Zodiac because it is longer and you have to deal with some loose rock and other logistics. As of 2015 there are only a handful of old bolts on this 1969 classic route, so take a bolt kit with you and spend 20 minutes leaving the route better than you found it(and better for the next generation).
