I keep the u's out of my favorites
mines 1.2-1.6 ohm 28 ga single coil, or same for dual (net .6-.8ohm) around 3/32.
for cloud chasing I do .3 24ga dual
coils around 5/64 or so.
I'm mostly using mechanicals, but the 28 ga builds do great on my hana clone too.
I use japanese cotton (Puffs organic japanese cotton pads on amazon - 200 sheets for like $10) a lot - or ReadyXWick from RBA supplies. The cotton is nice, the RxW is better because it seems to give off no flavor of its own and is much more heat resistant. I use a REO (bottom feed dripper) and dry burn & rinse after 6-12mls of
juice. I change out my cotton every 12-24mls depending on the
juice & build (some gunk up quicker than others)
Edit:
oh, and those are micro coils. all wrapped tight.
