From the current guidebooks (Rossiter's/Levine's), this single pitch starts with the broken crack on Fine Line to a large ledge then steps right and picks up the left-facing dihedral of the upper part of Terminal Velocity. An even better combo is to start with White Lightning. Pull through its crux and go up about 6 more feet to a hand jam crack. Step left and stand on a sizable jug of Terminal Velocity. Go up to the ledge and continue the dihedral.
This is a great first 10c lead in Eldo as it takes nuts every foot on the upper dihedral (the crux).
Standard rack. Medium/smallish nuts for the upper half. Maybe a small cam (blue/green Alien?) to prevent gear zippering in the dihedral.
