What's the difference between their different PPX lines? It looks like they have Detonator, Link, and Aspect? Is it just a matter of face shape? Which is which? And then they have normal and spherical, but they don't get into the technical differences, anybody care to explain?

Which did you buy and why?

If you're talking about the PPX line which is the photochromatic lens, it's spherical and adjusts the tint to the amount of light in the environment. They also have the SPX series which is just spherical and a bit cheaper. The styles are just designed for different types of faces and style preference. Excellent goggles but very difficult to find not on-line...
