Impulse is a worthy route, Transfusion not so much. The second pitch is one of the better 5.9+/5.10- trad pitches at Red Rock: dark varnished leaning splitter. The 4th pitch is a junker to the top of the ridge, the other two offer average climbing on so-so rock. The walk-off is definitely the way to go. Suit up down at the canyon floor and re-connect with your backpacks on the way out.
