The newest addition to the line, the SYNTELIAC ZCI, is one that could raise a few eyebrows, particularly when compared to the Butterfly Apolonia or Franziska blades. Personally, I am not familiar with these so I asked someone who is (and will always come back to the Apolonia blade from sponsor material...) for his opinion. In short, the ZCI is a little closer to the Franziska, a little harder than the Apolonia.
For me, it is even crispier than the VCO, while retaining that one´s phenomenal touch. The build quality, as you would by now expect from the Korean factory, is excellent. The blade works very well with tensor rubbers around the 47,5 degree mark, such as Rasanter R48 oder Evolution MX-P, and also with softer variants. I am sure it also excels with harder rubbers, but that exceeds my limits.
