Good thread choice
Most satisfying Multi-pitch was Zebra-Zion I launched up it having successfully led maybe three 5.10a pitches. What a stellar top out as well !
Most Satisfying single pitch is probably Kunza Korner down at Smith. Sacked up and led it on sight having never been on a 5.10c outside Though Paul Maul, and Stems and Seeds are close on it's heels as far as satisfying pitchs go!
How about scariest single pitch?
For me it was definitely Crackmaster Lambada out at Vantage. The climbing was right at my upper limit at the time, and varied between awkward bulges with little cracks that took tiny nuts, and flaring broken pods that wouldn't take any gear. I don't remember having any gear that I actually trusted to catch a fall. I hit the top and just giggling that I hadn't pitched off and pulled all my gear!
