You;'re flying to Paris tomorrow, yes? I am with you on London. It's okay, but Louisville is the whip for me. Muddy and murky with all low notes is the perfect description as far as I am concerned. London is great if you are oblivious to the better "versions" of similar tobacco mixes in liquids.
I'm with both of you, but enjoying London a bit more than you guys did. I prefer Louisville's blend and that tiny bit of sweetness. I think that London is very good, especially for those that want a no-nonsense tobacco that doesn't have any sweetness. I do agree that Devil Dog! is a better juice, but the blend is quite different to me. DD! is more potent and intimidating. London is mellower and has less Latakia.
I'm going to start dripping Paris now, just to get a head start on Jerms. Ha!
