After carefully examining the visors in the film, it becomes clear that they weren't as "flush" with the cheek plates and nasal cross as people tend to want to make them.
Honestly, velcro is IMHO the best choice, since you can re-arrange and tilt the visor as you need, and you can also easily remove/replace it WHEN (Not IF) it gets scratched or otherwise damaged.
With velcro I can get my visor flush with the nasal piece and as close to the cheek plates as any of the ones I've seen in the film.
I am using a Bluerealm rather than a Pinsky though, so YMMV.
