The "Justissimo" gets a definite thumbs up from me. In common with those above, my only gripes are that it's pretty noisy over 60mph and that it lets water in during very heavy rain - failings which are not as obvious in the Shoei version, I'm told. Other than that, I love the ease with which it can be donned whilst wearing glasses and the convenience/coolness of the darkened internal visor. I haven't removed the chin guard so I can't comment on it in "Jet" mode, though.
