Comments welcome, but please share your wisdom if you see something is missing.

If you read nothing else, please read the next 4 paragraphs.

Grateful Thanks!
I'm relatively new to the Oakley game (compared to some of you guys). I need to acknowledge the incredible contribution that the people tagged below, have made to this community over not just days or weeks, but years. Thank you so much for all the hours of hard work, lenses destroyed and money lost. I'm am grateful for your sacrifice and wisdom!

I've found this to be truer each time I've tracked down more information over these past few days.

We are "standing on the shoulders of giants". It's true what 12th Century theologian and author, John of Salisbury wrote,

"We are like dwarfs sitting on the shoulders of giants. We see more, and things that are more distant, than they did, not because our sight is superior or because we are taller than they, but because they raise us up, and by their great stature add to ours."

Introduction
This is a quick reference (and hopefully), up to date guide on what donor lenses work with which Oakley sunglasses (I've mainly concentrated on the X-metals).

I've compiled information from another forum and acknowledged the members who contributed.

Notes
Flak 2.0 (Asia Fit), Flak Draft (Asia Fit), and M2 (Asia Fit) are all slightly larger than their normal counterpart. Unless specified, all lenses listed below are standard lenses. For more info, click here (thanks to @DKO).

BC = Base Curvature. The lenses are curved to match the shape of a normal eyeball (BC 8.75). Anything less, and there will be extremely mild distortion to optics or more importantly, irritating contact of eyelashes with lens!

Yes - Yes, it works for cutting. You're good to go!
Yes, but barely - Yes it works, but there's not much margin for error. Don't try this at home.
Yes, but - Yes, it works for cutting, but you may have to accept some slight imperfections which may include vents or the wrong BC. In the words of @GRFMotorsports, "Just because it fits, doesn't mean its right."
No - No it won't work as it has been confirmed that someone has definitely tried it before.

So Here It Is!

Extras

Cutting lenses yourself?
Use a dremel with a fine rotery diamond bit then 1400 grit sandpaper for the edges (@SouLFuLFrog)
- Use an X-Acto knife to trace the old lens and cut a clean break on Iridium to lessen any chances of Iridium peeling. I don't use tape usually although I probably should. especially after cutting the G30s for this (M Frame to XS). I had a slight mishap and would have not happened had it been taped. But it's pretty minor (@VolcanOG)

Don't Know How?
Here's the short version of what you need courtesy of @ColdShotxx.
The tools used:
• dremel with a cutting disk, 80 sanding wheel, and 120 sanding wheel
• Fresh exacto blade
• Ultra fine permanent marker(very important to be this small!)
• Masking tape
• ENTIRE DAY FREE - it took me 2.5 hours to complete, but I had the mind frame it would take 10

New Turbine
BC is rated at 6, but measures in at 7.05 (@InfiniteHero)

Style Switch
Is a pollaric ellipsoid lens (@jdd32)

Other Lenses
Ikon are good, but slightly harder to clean than OEM. Their 24k lens is very good, +red and black have a slight greenish tint, but are otherwise very good. They seem durable, I've had mine in a couple of beater frames with no issues. (@NoFair)
