I know there have been a few threads about these recently, but there are a couple of things I'm still unclear on. I'm pretty set on the Flak Jacket but dithering over lenses - I know the non-prescription lenses can be swapped (as per this video), but can't find anything that says explicitly if this is possible with prescription lenses. Can anyone confirm/deny/baselessly speculate?
I had been tending towards Transitions, but if it's possible to swap lenses I'd probably pay extra to have two sets and avoid the whole "jack of all trades equals master of none" thing.
