Started off with Stonewall Big Slice 0mg and mature original Big Slice 0mg, upped both to 1.5mg then to 3mg.
Stonewall has the full flavour and vapour of the well-steeped version only the latter having a slight smokiness which is down to how old the nic versions are, both old and new 0mg virtually identical, the newer tasting fresher, so no surprises.
I would say the Stonewall ideally should be steeped for a week or two to let it mellow especially the nic version.
Love the 60ml bottles and no problem top filling quite narrow juice holes.
Success, Stu, you have the mannikon ©® seal of approval
Now to keep testing in various setups until it's all gone
