The LR Atty was made to simulate HV vaping and its close but not quite the same, it burns your juice faster and creates more vapor at the lower voltages. Something else you could do though which I prefer is to up the voltage on your regular Atty. I use a reg 510 Atty between 2.3-2.5 ohms and enjoy this much more around 4.6V than an LR Atty. This creates a nice thick favorable vapor without burning up your juice so much. Don't get me wrong LR's are OK but they are really hot, they spit juice up at your tongue and mouth and also burn juices a lot of the time and take away from the flavor at times. If you get the chance to up your voltage with some other variable voltage Mod than just a reg 3.7v ecig and get the chance to try say 4.4-4.6v with that Reg ohm Atty you may enjoy this more, I personally do, its all very subjective but I like a nice warm thick vapor instead of a scolding hot vapor
On the flip side some Mods that are only built for say an 18650 Batt that charges peak to 4.2 are very good with an LR Atty. It seems to me it all depends what Mod your using to achieve the best vape & Atty combo. Thus having a few different Mods is a good thing
