When first getting the Nautilus tanks here those still seeing the initial factory promo deal of two additional coils tossed in. The Atlantis had just come out as well as the start of a number of new smaller regulated box mods. At the same time I was looking to upgrade after two full years of vaping and wasn't looking at the high wattage simply for cloud making either.
What most won't realize at first since they are in need of getting adjusted to vaping since it is a completely different experience is the eventual need to boost things up a bit in order to get where they want to be if they should be starting off with the disposables or small 180mah cigarette look alikes and find those simply do not suffice.
At first here I found the Bloog refillable 20 drop blanks just weren't going to cut while I still lighting up and soon saw the 650mah batteries Bloog decided to smarten up by offering. Those were 808 threaded at first for their brand CE2 clearomizers and still lacking being the top coil long wicked type subject to dry hit issues. That is typical with the CE2 and CE4 while you will never see CE3s. The flavor for many flavors sadly suffer greatly when trying to make an accurate evaluation as I was still sampling for a new eliquids vendor until the business found itself off onto a good start.
The initial upgrade only brought in a few VV type batteries and then 14months after starting it was time to find better tanks and look further into VV/VW types of gear. The Tumblers still in use tend to serve well with the eGo type batteries while not able to get into the higher performance I was still looking for. The next upgrade was to bring in the Nautilus and Atlantis tanks as well as the higher wattage gear as the suggestions made for one business about not being able to produce quality vapor along with the excellence in blending was addressed. Once the new tanks were in the few flavors that vaped hot on the old CE2s suddenly saw a turn for the better as the increase in wattage with the improved designs of tanks made the difference overall.
As for cloud making the largest air holes or air flow depending on the type of AFC involved if present as well as the higher VG ratio if not 100% are what cloud makers will want. For the flavor chasers the 70PG/30VG ratio is the most common. Now for going with the latest tanks out that average 15-30w Nautilus can be still run low at 7w-10w for some older menthols that don't wick well. the average is 10-20w depending on the ejuice. For a sub ohm tank the average 20-30w is the most common while some flavors will want a higher 40w-50w. In each case the increase in vapor is available while the flavor is still present until dropping the PG level substantially. The fewer flavors that vape well at the higher wattage are lighter and wick much easier in order to still get a smooth vape and not a hot hit.
The Melo tank is based much on the design seen with the Atlantis and the vendors indicate you can still use Melo coils on the Atlantis tanks suggesting the same company makes both despite seeing a different brand name. Often what some label as clones are simply the change of brand name for the same thing. And since the Atlantis can bring out more flavor as well as see an increase of vapor production you should expect the Melo to do likewise.
I still run both as well as the Mini Nautilus and some Aerotanks depending on the mod in use. A mech epipe will a Kraigen Atlantis while the second regulated version won't fire below 1ohm. The mechs see direct flow through the switching on/off or locked/unlocked to the tank attached and why many opt for safety fuses. The Nautilus however works out best on the regulated epipe as opposed to several other tanks tried out. That runs 6-15w however while the Nautilus will still handle 20w when you have the right ejuice in the tank that wicks easy.
It's a quite a bit at first for most to even take in. And the simple fact is each will have to experiment a bit over time to find out just what is going to work the best for them. With just over $5,000 invested over the last 2 1/2yrs. time I will be adding a pair of Melo tanks plus some cotton coils for the Atlantis into the mix to place those up against the Atlanti stock coils and compare tanks. At first I only paid about $25-$28 with two extra coils for the Nautilus and $22 for the Mini tanks and $25 for the Atlantis by shopping around a bit. Most places want $33-$45 for those tanks while some will list them onsale to keep the prices down.
On the social networks in discussion groups there you will find too often is the cloud makers and RDA fans. Unfortunately that seems to be the most common trends while some still want to keep things basic as much as possible. The contract in pc terms would be those who prefer to run stock systems while there are those who want to OC. This is simply another area where some simply want a different type of bragging rights.
I think you are finding out for yourself what is working the best for you over time. The photos earlier where there to indicate what it can take at times to finally get into the gear that reach the intended goals. The point is that the investment is worth it in the long run as far as the potential health benefits of no longer smoking as well as some reporting improvements in COPD problems. In a 2014 news report the now Late Leonard Nimoy mentioned he had quit 30yrs. before being diagnosed with COPD conditions while accepting he was also up in age. So trying out a few tanks now to find what works for you is actually in your interest. Let the showmen worry about making the clouds!
