I had been saving "Crack of Doom" 5.11b/c at City of Rocks until I was strong enough at trad to have a chance of onsighting it. After a couple of years, I did onsight it. I did it the .11c way, too - not using the cheater holds, but pure crack style.
The "Bela Lugosi traverse" on Layton and my climb "Plan 9" in the Pickets was one of those moments where you don't know what is out there, but you go anyway. Overcoming gripping fear on an FA is right up there on the satisfaction scale.
