@Horton got it right...mostly. ;)
Through the 2015 model year, our speed skin material was white in color from our supplier. The colors were screen printed onto the material and we typically left the HO or Syndicate logo un-screened so in essence, the logo was the raw white speed skin material. As some have pointed out, minor scuffing of the screened artwork could occur along the rails or at the tip and tail. This scuffing is only cosmetic and if you look closely, the speed skin texture is still intact. Beginning in the 2016 Syndicate VTR, we worked with our material supplier and created a black speed skin substrate. This allows us to only apply ink on the logo areas, leaving most of the rest of the ski ink-free.
@wettek69 Glad our ski is on your short list! Assuming you are purchasing a 2017 Superlite CX, you will not experience any of the cosmetic scuffing occasionally seen in earlier models. As far as your question about PU vs. PVC cores... At the end of the day, PVC/carbon is better because it makes for a faster ski out of the turn. Whether you are skiing open water or are in the course, this is a big reason why most ski companies moved away from PU in their higher-end skis; people like the way PVC/carbon feels. I hope this helps in your decision process.
As always, I'm here to assist any way I can. Let me know if there are other questions or concerns!
