I ordered three helmets and had to choose one. It's become the SAVANT. And for only one reason: the seat / fit. Yes, Saros seems to be a bit more 'open', but both of MONZA and the SAVANT have enough air inlets so that one does not collapse to heat buildup. All have the same fixation system, the cushion from MONZA feel thicker on the head on, Saros suppressed a bit at the end. I had all in white and silver, and Danz honest: It really was not as easy to distinguish them.
Therefore: do not decide on the model ("I need the high-end model that the famous cyclist X bears"), but to fit.
