Please explain "practical reasons" ?
I have this new dripper that does 1, 2 or 4 coils. I have 1 on it now, but can't figure out why I might want more LOL
I used single coils for a while when I started with rebuildables. My first one in early 2013 was a Genisis, an AGA-T which only handled single coils and the thought of trying dual coils in a Geni never appealed to me because of the complexity of handling shorts with SS mesh.
These days I always use at least dual coils when I can in both drippers and tanks. I find they vape better for me than singles and I think it may be because the power is split between the two coils and wicks so each is actually doing half the work. With mech mods it also makes it easier for me to get to the 0.2-0.4 ohms that I like with these setups while still getting short heat up and cool down times. I also think I can go a little longer between cleaning the coils with duals. My most used juice is a DIY recipe that is quite dark and gunks fast so that's good for me.
A few months back I got a Psywar Onslaught that has four posts, one positive and three negative that handles one, two or three coils nicely. I've been running it on a mech mod with three 27 gauge coils at about 0.23 ohms and it's become one of my favorite vapes. It's not too aggressive, just barely what I consider a warm vape and it has very nice flavor.
I've tried quad coils in a Mutation X but that RDA is not made for them and I went back to duals in it.
All you can really do is try duals and see for yourself how it vapes. Once you know how the single coil setup performs in the same atty you have that to judge it against. It will definitely change the flavor profiles of your juices. Weather you like the change will of course depend on your taste.
If you do decide to try it sometime let us know how it goes
