I am honestly NOT convinced that JUST because a thing costs more it is better. Squawking Pidgeon Harleys would be an example.
I have always happily spent money to get the best - if it really is. But part of me wants to follow the 20/80 rule. - I am probably more a 50/95 mentality.
An example btw IS the Shoei GT AIR which only gained 3 stars in the SHARP tests as opposed to other cheaper ones.
Shoei GT Air - SHARP
It still surprises me, and often, how often the "budget" lids get stunning SHARP rating -
I know this is not the ONLY resource - but it is to remark upon.
When I bought my current lid - on the list was "must have a SHARP 5 star rating". OK I would have accepted 4 - but certainly not 3 and below.
A lot of fibre lids seem to fare poorly in side impact tests - odd really.
I have had a NEXX and it was OK but not perfect - but have read the latest 2017/2018 family have a different head shape.
Had Schuberth too and they don't fit me all that well. Plus the new ones look - well - sort of ................................... odd.
Arai I cannot comment on. Somehow I have always had an aversion to them - irrational but there it is.
NOISE : A concern but I always wear plugs these days - will never need comm's etc.
White or Hi-Viz - Hmmmmm.
