I would wait until you buy that updated wing..... maybe by then all the helmet manufactures will have all new helmets.
I don't have one yet..... but I really like the features in the Arai. Especially the fact they have both a face shield and peak visor at the same time. ..... I need to find a shop that stocks these so I can try them on for myself. ...... but I live in a dusty village with no such shops.
