Galfer Wave Center-lock rotor: Real weight (VS 6-bolt & Shimano)

Thanks to my mate I got a chance to weight the Centerlock version of what is my go-to disc rotor the "FIXED DISC WAVE" from Galfer (I use the 6-bolt version)
A little comparison between the CL and 6-bolt as well as with Shimano's top of the line models.
