Climb bottomed out seam for about 50 feet until you can start to free climb(don't fall on your aid gear because it will all rip out) Easiest way to the top is up and to the left on a 5.6.
Location
On the west side of pinnacle peak, climb up the gully to sundeck boulder and walk around to the the right and you will see a crack line that obvious that it is aid, crack goes up and moves right.
Protection
Rurps knifeblades(shorties), mico nuts can fit in pinscars.
having done this 1/2 doz times, it is closer to A.2. Some solid rurps to a nut about 20' off the deck scratch the bad fall factor of a real A.4. I am pretty sure a tcu fits higher still. The best nailing at the peak.
