Andria, if you use RBA's just wind your coils to a higher resistance. I run a Kayfun on top of the iiStick at 2.5 ohms or thereabouts. IIf you don't rebuild, you'll just have to make sure you can find coils 2.0+ ohms. I vape the the Nautilus Mini using their 1.8's because that's the highest Aspire provides in the BVC variety. Yes, it's a bit too hot for me but iif II open the air flow wide open and it this makes it manageable.
The iStick certainly doesn't vape lke the MVP or VV3 at the low end and I also think it uses averaging. But us low wattage vapers are in the minority and this doesn't affect most.
Well I do use rebuildables, usually a Kayfun, for which I use coils usually right around 2ohms, or I use high-ohm cartos, but I probably won't get an iStick, for just this reason; I vape at pretty low wattage, usually about 7-8 watts lately, though I go up to 10-11 watts on my Vamo, for the UDCT, just because the Vamo seems fairly underpowered compared to my vv3s or Sigelei.
But anyway, didn't the OP say "no box mods"? Thought I recalled that from the 1st post. And i believe the OP is a fairly newish vaper, who may not be up to rebuilding coils at all, hence my earlier comment that a newish vaper might not know how to handle a mod that vapes so hot.
