I am interested in your thoughts about the micron head design. Here are the three micron heads produced by Olympos: Here is a picture of the micron heads from my Iwata CM-C+ (left), and my Olympos MP-200C (right). Ignore how dirty mine look. My Olympos is the L3 design. My Iwata looks like the S3 design. The Olympos website states that the differences are subtle. I disagree. I think the difference is very noticeable. The psi and performance are very different. I can even hear the difference if I were blindfolded. I know several members here own, or have tried both styles. What do you think? Any preferences? @DaveG which head design is the GSI Creos PS-770? To me, the L3 is the louder, higher psi of the two. I think it is also a more narrow cone spray also. Whereas the S3 is more delicate.
