The Batwolf and Oil Rig have simular sheilds, but the Oil Rigs are a little smaller and are more squarde with a little more light leakage. The stems on both models are obviously different, the Batwolf has the Fuel Cell stems (which I love) and the interchangable icons. When I first got my (Shadow camo) Oil Rigs I notice they were really light but the stems felt really loose and not super solid. Now when I got my Batwolfs (matte black) I liked the sturdier feel of the stems and frame. My personal favorite is the Batwolf you get sturdier ear stems and interchangable icons. While the Batwolfs are slightly heavier, Im willing to take a heavier frame over a lighter frame.
