Thanks,
This is the Ryet one I have: https://nl.aliexpress.com/item/1005006354098277. Probably the wide flat shape is worse for me than the actual hardness.
It's correct that the Selle SMP saddles are hard as well but if the shape fits that is ok. Would you say that the Goldix shape/ fit is comparable to the SMP?

I was asking about the hardness because I do have another 3D printed one from LightCarbon, the SD01 which is very soft. Maybe too much so I found in the beginning as it was fine on the sitbones but it caused my butt/ leg to go to sleep after 1 hour. Over time with finetuning the angle it has grown on me and now feels very comfortable even on long rides without causing numbness.
Unfortunately LightCarbon charges $75 for shipping a saddle to EU, the same as for a full frameset. Hence my continuing quest....

I would say that Goldix shape is quite good. I like evo's shape most  and  second docici ( https://www.aliexpress.com/item/1005008391335012.html?spm=a2g0o.order_list.order_list_main.510.7d0d18023RaRLn ). Third would be goldix and fourth Selle Smp dynamic (i dont like its shape. It is too round? for me)

Velobuild is stopped selling smp clones so is there any cheap alternatives? Or do i have to buy smp well saddle

I found this one. https://vi.aliexpress.com/item/1005008391335012.html?spm=a2g0o.order_list.order_list_main.5.7e911802WCYBnP&gatewayAdapt=glo2vnm

Surprisingly comfortable. I have tested on a trainer couple (~60min) of rides whithout padded shorts and no issues.
