When using a mech, you need to determine what your battery is looking like after load and voltage drop. Use Ohm's law to target your preferred Wattage, i.e., 7 Watts, as an example, then build your coil to match the resistance required to achieve the Wattage with the voltage output. Low Ohm's, in and of themselves, don't provide a good or better vape. It's the entire equation, including the coil, the topper, the juice, the battery, etc. While all of these variables are easy to sort out, in other words, you don't need a degree to work them out, you do need some experience and a good bit of knowledge. The Ohm's on the coil must be targeted to work with all the other parts. Suggest you review the many helpful threads in the RBA section, ask questions there, watch a bunch of videos, quit chasing clouds, until you understand everything, and enjoy a sweet hobby. This is an advanced topic for experienced vapers. Take it slow and easy, have some patience, you'll get there, and it can be the best vape of all, imho. Good luck and thank you for sharing such an important topic. Best to you!
