Interesting you say that. The coils I build are usually around 1.2 ohms and I vape at around 8.5-9.0 watts. I see the 1.2 and 1.6 ohm coils are suggested to start at 10 watts.
Yes, everyone is different - personally I rarely use more that 8 watts and use the 1.6 ohm coils on my Nautilus Minis, my Zlides and my Zeniths. all filled with 16 strength liquid.
It probably won't make sense, especially to Americans who probably never experienced them, but I can only explain it thus - back in the day I loved unfiltered British Virginia cigarettes.
My two favourites were Senior Service ( softer but rounded flavour and very satisfying ) and Player's ( mellow but sharper in taste and very "more-ish).
I see Nautilus Tanks as being akin to Seniors in the kind of vape they give and Innokin tanks as akin to Player's - but that's just me.
