Climbed with Bob, on an aborted attempt at a spring dayhike of Snake Dike. Returned via LeConte Gully. Great fun, even without Snake Dike, although I wouldn't repeat it--the NW Face of Half Dome is a bowling alley at times in spring, and the climb up to the Diving Board via the slabs is unacceptably dangerous at this time IMO.
The slabs offer a shorter, but tougher scramble to reach the Diving Board. Doing it in spring can be dangerous however with hard snow on the exit. Trip Report
