East Face of Teewinot, Owen Spaulding route on the Grand (one well-protected 5.4 move) are a couple. Though the CMC Route is a great choice, because the bivy setting is awesome, the approach way cool (via canoe), the sheer size of Moran is awe-inspiring, and the crowds are low. Heading back to Moran (and other Tetons objectives) myself in July if all goes well!
I would say the exum ridge on the grand. Much more sustained technical climbing than the owen spaulding; a lot of scrambling mixed with roped pitches. It's 5.4, but a gunks climber would probably call it 5.3. Big crowds (guided parties, etc.) but not much rockfall danger til the descent.
The east face of teewinot is close to as much fun as I've ever had in a day, but it's all scrambling. Haven't done the CMC yet but look forward to it as a great adventure (canoe portage might be the crux ...)
