Hello, this is my first post after much lurking. I have a 2d Mag and a 2aa mini mag. After a recent post here I think the Arc aaa LED will be my first new purchase. I work in live entertainment production and performance and am often in need of a weatherproof, durable light. I'm also wondering what mods I can do to my Mags? This looks like a great forum it has a ton of information. Which one? The Arc aaa or the CMG Infinity Ultra?
