do i just build normally as i would but two coils?, as before i was seeing you have to look out for pos + neg poles etc, plus the high vg juices are driving me mad, they just don't taste nice at 15 watts, maybe it's just my builds but i put some Dinner Lady Lemon Tart in my Squape Rs earlier, and it was just mute.... but there's such a big selection of flavours in the Sub Ohm category.
