In addition to Gritscone, Squishy Bell (also in the Far Side area) is entirely top-ropeable. Unlike Gritscone, which is entirely under tree canopy, Squishy Bell is open to the winds, and faces East/South, so it might be dryer; it certainly is sunnier. It's about 20 minutes' hike from the parking area (If you follow the trail that goes past High Point, and Eastern Block, once you hit the talus field, skirt along its lower/left edge, until you see the trail that goes left of the talus field, and takes you to Squishy Bell: the trail is not obscure, or particularly faint, but is a lot easier to find once you've seen it once, and can be missed the first time around).
Write-off-Rock in the Deception Crags area can be top-roped, after you lead the really short and easy 5.5 (Exit 38 rating) on the left. FWIW, I thought that 5.5 was a nice, gentle first sport lead. It may be possible to scramble to the top of Write-off-Rock, but I suspect that'd actually be harder than leading the 5.5 on the left. Write-off-Rock is about five to eight minutes' walk from the Deception Crags parking lot.
Beware of credit card stealing car-prowling shysters when you go to Exit 38: take your wallet with you to the base of the climb.
