While this is a variation because the other Pony Express was done first, this is actually the direct line. Do Pony Express through the first pitch and into the second pitch. Where the climbing gets hard and Pony Express traverses left into the crack and arete, keep going straight up. This is the pure dihedral line straight up and adds some very technical stemming/palming moves.
Think of the first pitch of Aerial Book but harder. My guess is that Roger Briggs was doing yoga when he did the FA of this. Stretch before you try this.
You can link Iron Horse into this for one stellar 130 foot pitch of 5.11 climbing. Go do it!
Location
Climb straight up Pony Express but don't traverse left to the arete. Climb up the wicked, stemming dihedral.
Protection
All the regular stuff for Pony Express but some much smaller gear for the crux.

This is the variation mentioned in the Pony Express Page: "Going directly up the corner the whole way is thin stemming (5.11d) and is not as well protected." I don't think that the gear is bad per se, but it is not always where you'd want it, nor bomber.
