Aspire offers 2 coil options when it comes to the Breeze and Breeze 2.
The first of the two, the 0.6 ohm option, is the more flavorful of the two options. The 0.6 ohm coil works well with both salt based nicotine liquids and classic nicotine liquids.
With that in mind, it is worth considering using the 1.2 ohm coils if you are using a reasonably high nicotine strength.
Coil life between the two is very comparable, although use of more viscous normal nicotine liquids with the 1.2 ohm coil will result in a shorter coil life.
