ok so ive had my SB and Omega for about a month or so and just got a v3 from the classifieds. my hing is im noticing more vapor with the SB and omega vs the v3. now im not really understanding why but the 2 reasons i could come up with are that the v3 uses the 17670 bat and the SB and omega use an 18650. the other reason to me could be that the hot spring in the SB and omega make it run a little higher than 3.7v. if anyone else has noticed this please chime in as i am using the same atty and juice but noticing a smoother vape with more vapor
