As try as I might I have a bad case of ordering everything, Currently have a Snow Wolf 200, IPV4s, Sig 75,and A ipv D2 if it ever gets here, That just my Temp controlled, My Question is which one would you prefer and Why? I know that the Sig have a better track record, But I am liking some of the features of the smok. If anybody has any insight on one or the other, or both for that matter I am all ears.
