I ha\/e a kit that was mailed out to me today I should get it in a few days that comes w/ the 2 eGo Bats and 2 atomizers, But I just noticed it says 1 Atomizer is LR (low resistance) and one is SR (standard resistance). So I googled to see what this all meant and all I could find was that (this is from my readings) LR atomizers.... die quick? Can someone explain to me what the real deal is between SR and LR. Also how one would go about using them differently if necessary. Thanks
