I, too am considering either a Nexx or a GT-Air. The benefits I like with the GT-Air is that it already has the pin lock visor included and I wouldn't need to change visors because it has the drop down visor. With the internal visor down, it looks like it already has a smoke visor. I like Nexx because of its light weight and wide field of vision, but I have also read reviews about its poor construction and how it starts to fall apart. I am curious to hear from any of you who have these helmets. I would like to try them on, but its not widely available here in SoCal, none that I know about anyway.
