Okay, so have been using the Tour X4 now for a few weeks and generally very happy with it. Very comfortable and noise wise its maybe not the quietest but OK, Slightly heavier than my previous helmet but even after long days on the bike not been an issue. Ventilation seems to be very good with lots of air flow which was great on the hot days. Only thing I'm not sure about is that even when i close the vents, still seem to be getting a flow which might not be ideal when really cold.
All in all very happy with it and would recommend it.
