Worry is, I have now 3 options.
Or active DD67000 (original enclosures), or 'monsters' with 4367 lens , or M2 lens (made cabin's CNC drafts already, material didn't touched yet).
JeffW was right - there comes options. Came.
And as 476 is near-impossible to get then it's not a problem anymore either: Radian 951 (with another label of cause) is new 'official' 476 at Everest.
Only questionable thing is 045 ... if go Everest.
