We present five ignition scale capsule designs using high-density carbon ablators with fuel adiabat (alpha) ranging from 1.5 to 4. All five have 1D yield > 1 MJ. The sensitivities of these capsules to surface roughness and P-2 radiation asymmetries were studied. The most robust configuration with respect to surface roughness depends on the amplitude of the surface spectrum. The most robust configuration with respect to P-2 asymmetry is the alpha = 1.5 configuration which has the highest 1D margin. We find that alpha = 2 and 2.5 configurations have the highest overall robustness. Further analysis is needed to study the effects of more complicated 3D behaviors.
