I have fallen into the variety type of vaper too.
For almost 4 years I used an Odysseus and ONLy that. Mostly because Im lazy and I "knew it" and gave me the performance I needed.
About a year ago, I gave Kayfuns a try and they did not like me. Either I had flooding or dry hits. My builds were never consistent. 1 in 4 builds were perfect, then the others were not.
I hate to buy and spend on atties that I end up not liking. Im basically a tootler. I like clouds but flavor and consistency is priority. I need to set it and forget it.
I now have Origens for dripping hardcore NET and a pair of Taifun GS2 for lighter less gross NET.
I have Phenomenons Zests" by GUS for special lighter flavors and for relaxing. For most its a sort of a medium draw, not tight , but NOT something you chain vape or use when stressed or going out.
Then I have some Taifun GSLs and FEV V3s. Those are my bigger clouds, hit it stressed and chaining. Flavour is just as good as on the Phenoms but much more air and clouds.
My favorite , most consistent, reliable, swear on for reliability , ease to setup, is the FEV3's . They are not the prettiest or stealthy but I know they will work, and I can set up with my eyes closed if I had to. I can pour liquid in straight out of the bottle, no mess unless I get real shaky,
I also am a single coil person. For me I only see that the liquid gets sucked up faster.
