Sorry about that! I'm using Kanger Protank 3 tanks and replaceable coils. I'm not sure what ohms - I'll go check.
Edit: 1.8 ohm replaceable coils. Using a MVP 20w and adjusting the power to get a good amount of vapor/ throat hit without being too much and trying to avoid burning the juice.
Oh, flavor of juice - a really nice menthol from Vaporbeast called Ice Box. It has a subtle tobacco flavor but it's mostly menthol. They do their juices at 70vg/30pg and mine is 18 mg nicotine.
Cool.
The PT3 coils come in a variety of resistances--your MVP will only fire down to 1 Ohm--so make sure your using 1 ohm or above.
Been awhile since I used my Protanks but I do believe they still use a silica wick vs. cotton wick. The nice thing about silica is that it is more heat tolerant than cotton. (If you dry fire a cotton wick it's 'adios muchachos' and needs to be replaced). If you cranked up the wattage on the silica while dry it is possible you burnt that silica and will forever and anon have a burnt taste on that coil. Throw it away.
While I have had that happen, I've never had that taste linger on in the tank after replacing the coil. But if that happened, disassemble and clean using a grain alcohol, vodka or distilled vinegar.
You can also clean the coils to get some extra life out them. I used to do this religiously each weekend. I would pull out the coil, soak it in vinegar/water for a couple of hours than carefully "dry burn" them (pulsing the coil til glows) and gently brush off any residual gunk on them with an old toothbrush. However I was vaping a heavy, dark liquid while it sounds like yours is the opposite. I quickly got lazy and just vaped them til death then learnt to rebuild them (I'm a cheapskate). I now have a mix of rebuildable devices and replaceable devices.
If you decide to move on to rebuildables there's some cool stuff out there but the nice thing about the replaceable coils is that you just screw in a new one and go.
It's all about what you want.
Adjust to taste and enjoy.
Sounds like your weening yourself off the smokes (which IMO is the best way to go vs. cold turkey). Don't beat yourself up if you cave occasionally:
Everytime you vape instead of smoke it's a VICTORY!
You will get there.
BTW: I'm was never a menthol guy, but HALO ecigs has a wide variety of menthol varieties. Also a friend of mine tried Johnson Creek Silverthorn menthol and said it was the best menthol she ever tasted.
