I did notice the protruding chin in a couple photos. In my case, however, I think I will be OK. I have microcephaly - not really, but do wear a XS helmet. In fact, one of mine is a youth size large. Went that route to have a smaller shell size. So think my little melon will not be so long as to protrude underneath.
As for the comments on the weight and visibility, I don't expect weight to be an issue as the helmet is made with modern materials. The perifery I think will be OK for visiblilty, but might be a bit resrictive in the lower field. As it is, I can't see my instrument lights without looking down when I have my Scorpion full face on, so am already a bit restricted.
