Smith Attack MAG MTB Sunglasses

The Smith Attack MTB went right to the top of the list of riding glasses on my list shortly after their debut. I am a full time contact lens wearer & to ride fast & loose in contacts, it's a must to have riding glasses. Grit in your eye with contacts is agony & wind can dry contacts out without a wind barrier for the eye.
Needless, it means I've ridden with riding glasses since the mid-90's & am picky. I've got chubby cheeks, a narrow nose & only ride up because that's how you get to the descents! My requirements are simple...don't fog, give me almost clear lenses for the dark green shaded forests of the southeast & let me ride until dark without taking them off. 
The Attack MTB was a big draw because of it's frameless design, size close to that of the goggles I tend to ride with on most trail rides & the ability to easily swap lenses.  There are zero reviews I could find online so I took a leap of faith in ordering direct.  The fit indicates medium fit/large coverage.

I've managed to ride in these in everything from bone dry spring drought to pouring non-stop 2 hour rain & follow that up with rides in the steamy, muggy aftermath.  The quality of the design is great, adjustability of the earpieces & the comfort of the materials are well thought out.  But the abilities of the glasses is utterly neutralized by the nose piece.  

The nose piece has a single "click" to make the bridge wide or narrow. Wide is huge & the narrow setting is not quite right.  It places the lens firmly within just a few millimeters of my temples & cheeks, not allowing any circulation of air & trapping heat & moisture.  On my rain ride, the lens shed rain easily, but the anti-fog treatment had no chance to do it's job because there was no way to set the nose bridge far enough off of my face to allow air flow. My last few rides were in steamy conditions after the rains as everything is drying out and the moisture on teh inside of the lens rendered them useless (see photos below taken just 10 minutes into a steamy ride).

The low light lens has great vision for shadowy everygreen and rhododendron forests but the dark tint lens that comes with my moss frame was too dark for MTB unless you live in a treeless environment or wanted to use them for road riding, so I essentially could only use one lens.  With a performance frame like this I'd prefer to receive a standard chromo-pop lens and a clear lens, since it is MTB specific (it's in the name).

These glasses would be better labeled as LARGE because you need a very substantial nose bridge even in the narrow setting for them to serve their function.  I have no doubt that if they sat only a few millimeters off my face, all would be golden, but the lack of a realistically sized nose bridge neutralizes all benefits.  

Last small issue is that the low light lens air duct/bridge is not the same color as the frames for some reason.  It's black?

I REALLY want to love these things though.
