Exit Stage Left is a complete route, done in 1979, but no one does the lower pitches as they are very dirty. The last pitch is an exciting bit of climbing and it's worth your time. I did the section up the GT ledge once; it was pretty non-descript. Dick's guide lists the last pitch of Exit Stage Left as Variation 1, but he incorrectly credits Mike Schneider with the first ascent. Schneider did the 5.9+ variation, listed as Variation 3. Neither Willaims or Swain has any info. on the 5.10 variation.
