I ran exclusively RM2's for years, but now it's Vapefly Galaxies. No dry hits, plenty of MTL flavor.
I like the Galaxy and the Wasp Nano. Around 15 Watts and 0.8 Ohms, a single simple coil. I am not precise but that is the neighborhood I shoot for.
I especially like the Galaxy when driving, you have to work to get a dry hit, makes it easy to tend to what is ahead, around and behind.
