Another question, which bvc coil work with these? The mini nautilus one's?
No I think it's ones that came in my last couple tanks I bought the Eleaf GS Air (Great tank for 13 bucks I ain't kidding!)These ones?

Scarf, welcome to a great thread. Love my Egrip too.
Wattage does effect wick longivity and when it's spot on, vaporizing the juice at its optimal temperature, your wick life can be greatly extended. But too low of a power level can be just as detrimental as too high. At insufficient power levels many of the components of the juice remain in the wick and are not carried away in the vapor. They collect there and cook into the wick and sooner than expected your wick is producing nasty burny tasting vapor. Conversely ,too high of a wattage setting can burn juice into the wick as well but at least it is easily detectable early on.
So where's the happy place? It depends primarily on the juice pg:vg ratio and added flavorings, but as a general rule if you run your wattage just below the burny taste point of the juice you will achieve the longest wick life.
Example. When running dirty naturally extracted tobacco blends in my dripper at 30w I can vape about 3-4ml before wick change/dryburn. At 40w I can vape 10ml. Same thing on my Protanks and RTAs, running at the highest wattage without a burny taste results in the longest wick life.
I have never used the CS heads for the Egrip but would try setting the wattage higher than 8 watts; could be helpful for wick life.
As a general rule I have found that flavor intensity follows as power levels are increased as well; up to a point. That point being just below burny taste.
So perhaps you're thinking, "my battery life is going to suffer if I turn it up"! Not really with regard to mils of juice vaped per charge. If you turn your wattage up 25% but take 3 second pulls instead of 4 second pulls you are actually using the same amount of battery mah but are gaining the added flavor intensity and increasing wick life. Win-win imo.
So I've git some q's for those who are building coils for this rba....what gauge wire are you using, and coud anybody put up pics of how they wick it?
My homemade one leaked a lot, and i found one of the original 1.4 ohm coils and put it in, but its gurggling a ton, on any setting, i can't figure out why the first preloaded one worked so awesome, and its proper replacement doesn't.
All my premades gurgle a bit, no matter how I wick them! I haven't yet made any though, but I can't see it would make a difference.
I figured it out. When I was rewicking or replacing them, I positioned the wicks upward, almost parallel with the coil, this allowed more liquid in the the unblocked holes at the bottom. So this time i took the top caps off, pushed the wicks towards the deck, and put the caps back on.
Now it vapes like the day I bought it, holy cow. In fact, I may even move them back up, just a little. Its a vape monster again.
