I'm lucky that I'm able to get along okay with any of the racier saddles, Fizik Argos, Pro Stealths, SLR boost, etc. My favorite saddle, before the 3D printed one, was an SLR boost. However, I had issues with the durability of the SLR and wrote them off. That being said, my ass would be a bit sore after any long 4+ hour ride, regardless of saddle. I spent a little over 6 hours on Sunday on the 3D print Argo, and didn't even think about my bum. For me at least, the 3D saddle conforms better to my sit bones, and there were no pressure points...I was skeptical at first, but now I highly recommend them.
