The previous blog entry showed a portrait of an Indian yogi that I sprayed mainly with the Iwata HP-BH which is a gravity feed airbrush. The HP-BH I found to be performing even better than the CM-SB in spraying ultra fine lines. Probably because the HP-BH is gravity fed. There has been a lot of discussion about which system is better - Gravity feed or (side cup) siphon feed. It is possible to combine the best of both worlds. Testor (maker of the Aztek airbrushes) offers a side cup that fits snugly into the CM-SB, as do all separately sold, dirt cheap paint cups from Testor.
