"Bent Gate, Anodized" has the yellow gate with a gun metal blue color body as in the pic above.
"Straight Gate, Anodized" has the gun metal blue gate with yellow body.
"Bright" ones are raw polished aluminum bodies with colored gates. But the gates are opposite the colored bodies. Bent = yellow, straight = blue.
EDIT: I 4got to add that these biners are the bomb!
