LG HG4 is really not bad, do recommend.
Yours take awhile to ramp up probably because your wire too thick. What gauge are you using? Thicker gauge = longer ramp up.
For 18350 mod, I usually build 1 ohm and up, usually 1.3ohm.
For 18650 mode, I build lowest 0.5. Depends on your mod, some mods can't take low ohms due to button wear or hot button.
Using 26g, 6wrap dual coil at around 0.5ohm gives me lots of cloud and flavor. Cloud very dependent on your atty too. You want clouds, get a mutation or Kennedy. Flavor stick with small ones like derringer and marquis.
Good luck building man. Learn about battery safety, very important. Good batteries are Samsung 25r (blue), Sony VTC5(green), LG HE2 (red) or LG HG2(brown).
