Detox was one of the rings I've noticed, I have only 2 guidelines, the scope of wind and the price, I m sorry, but detox would have to buy 3 models, std, semi end vented. When another producer covers range 5 - 32km/h one model. As for the price, in my country, the euro c is 4x1... will decide to make one model with a wider wind range. Although I do not hide that detox (extra) will definitely be in my bag at a later date.
