lol, you're allowed to have questions... we all did, and do.

As to that general statement, I'd say that's flat out false. People say that rather generally because when someone talks about a 'dual coil' ie dual coil that comes in a dual coil tank, they're usually in the 1.25-1.5ohm resistance range. A more accurate statement would be '1.25-1.5 cartos are not suited well for the LT', simply because they won't allow you to get out of the 3s, voltage wise. I love my 1.7ohms, and they're not much higher than that, but they get me close to 4.4ish volts, and that's perfect for me. I couldn't tell you the exact difference between the two, but its my understanding that dual coils LITERALLY have two (ie: dual) coils wrapped to create lower ohms... which is why, like Videodave mentioned... if you have a dual coil in a very low resistance, you can 'snip' one of the coils, and end up with a single coil carto at twice the resistance of the original dual coil. lol As to my taste, the vape 'feels' different to me at dual coil or single, and i personally prefer single, but LOTS of people love dual coils. AND now there are dual coils available in 2ohm, 2.5, 3ohm, 3.5, 4ohm... any of those would work just great on the LT. The general 'LT's don't like dual coils' thing came about initially when tons of people bought em when they first came out (which is incidentally when dual coils were at their most popular, if I'm remembering correctly) and loads of people were frustrated that the 2.5amp restriction stopped them from vaping a 1.5ohm dual coil in the mid 4s... So moral of the story is, dual coils are great on the LT, but unless you only want to vape at VERY low voltages, aim for one at 2ohm or higher.

Hope that helps!
Oh, and of course there are exceptions to any rule. I have a 1.5ohm dual coil CLEAROMIZER that I love on the LT, because the carto itself is so intense that the ideal voltage for me on it is about 3.5 volts... those are these ones...And you can see, all the reviews talk about how intense they are. BUT with a regular old smoktech dual coil in 1.5ohms, 3.5v just wouldn't seem 'intense' enough... so it has a lot to do with specific cartos, also.
