I'm undecided on these but leaning towards no. I'd prefer options for CR-39 lenses (the lower weight makes up for the tiny optical quality trade off) and different colored lens options (green).
Deviltooth@Deviltooth you can get Polycarbonate, or Nylon lenses from Randolph. Much Higher Impact Resistant to CR-39, just as light weight. Also check out Randolph's AGX lens or there new Jade Metallic lens for the green color.
TimZaleskiThank-you TimZaleski. I'll look on their site... though it would be nice if Massdrop ran another Randolph drop this time with alternate lenses (or more options like we got with Shwood).
