Are you direct dripping or using a cart? If the VT juice seems thinner, then I'd definatly say the liquidxpress juice is VG or has some VG in it. You'll get crazy vapor from VG, but you should still get good vapor with VT juice also. What flavors did you get from liquidxpress? I'm wondering if since the VT juice is thinner than what you're use to if maybe you're flooding the atty a little. After you've cleaned out the atty (just roll up a piece of paper towel and insert it in the end and leave it for several minutes, remove and repeat), try using only 3 drops of the VT juice and see if that helps.
