Frame: X-metal, TiO2, Plasma.
Lens: VR28 Black Irid Polarized, Amber Black Irid Polarized, (+) Red, Ice, & Black Iridium.

Of the x-metal line, the x-metal XX and the Romeo 2.0 fit me the best (med size head). The x-metal XX's are hands down my favorite frame! Lens coverage on these are awesome!

N.B. - I'm going to call these 20's for the rest of the review because that's what I call them and it's shorter than typing x-metal XX. ;-)

A lot of people think of the 20's as a larger Juliet, but I think they are different enough to not think of them as such. While the Juliet is beautiful in it's own way, these are more subtle in the design area. Around the lens orbitals, the Juliets are more linear and have much more pronounced lines, while the 20's have a larger and smoother shape to them. Also, the hammered earstems are a nice touch of design style on the 20's (and only available on the polished Juliets).

The only downside to the 20's is the lack of factory lens colors offered -- you're pretty much stuck with Black Iridium, except for Ice Iridium on the Plasma frames. Cutting my own lenses gives me a wide variety of lens color options to suite my mood. =)

As far as frame finishes go... This is very tough, but it all comes down to the lens color combo you go with. IMHO, I think the following...

The X-metal frame is nicely offset with vibrant color lenses (e.g. (+)Red Iridium).

The TiO2 frame would look best with softer colors (e.g. VR28 Black Iridium).

The Plasma frame can compliment just about anything.

The 24k frame I won't comment on as I don't own a pair.

Any color frame you go with, you can't go wrong. ;-) I would recommend this frame to just about anyone. The 20's are less linear and a little less aggressive than the other models within the x-metal line. I think this makes the 20's more versatile in being able to fit a larger variety of face/head shapes. Try on a pair, you won't be disappointed.

I got these at a discounted price off the internet, and I love them. The Titanium frames hold up very well and the gold finish looks very nice. The 24K lenses are my favorite lens to look through. Unlike the similar Fire lens, your view doesn't turn green, but more of an orange, but mostly, it just darkens. This pair is similar to the Juliet's in style, but has been stretched upward to make the lenses higher and cover more area around your eyes. If you have the money, I highly recommend these to anyone.

I was always a fan of the Juliet and the XMXX is very similar in shape to the Juliet. The biggest difference is that the XX lenses are little larger (taller) than the Juliet, and the ear stems on the XX are hammerstems, the slighly tweaked earstems. The only Juliets to come with hammerstems, are the polished and Ischiro versions, while all variations of the XX had hammerstems.

The larger orbitals allow for more coverage for those with a little larger face. I really like these compared to the Juliet due to the slightly larger size. I did not realize how much of a difference wearing the XX would be compared to the Juliet until I actually got them on my face. I was surprised at how much more I liked them. I started out with more Juliets than any other X-Metal, now they have taken a back seat in my collection.

The only downfall that I can see is that there were far less colorways on the XX than the Juliet, and they were discontinued a longer time ago, so they are slightly more difficult to get a hold of, and thus cost a bit more, but they are well worth the trouble if you prefer a larger frame or have a medium to large noggin.

These glasses were perfect for me, I'm 6'10" and the glasses had perfect coverage. I was going to buy Juliet's or Penny's and they were both too small for my face. Had these for over 6 years and they are great. Too bad Oakley doesn't make rubber for these anymore.

Finally got to wear these after they've been sitting on display for over 6 months. The fit is great and the 24 k of the frame makes excellent contrast points.

A bit bigger than the juliets, these still offer great coverage and a more "in" look if the juliets fit you.
