I'm a tank user. It is dependent on having good quality ss replaceable cartomizers. Pre drilled cost more than drill your own plus drill your own can deform them enough to to slide thru a good tank properly so start out with pre drilled that small hole with no slight bulge around them. Single hole is good if you use a thin juice, don't vape hyper heavy and do periodic cold draws to keep the inside of them wet. Sometimes I even drip several drops to "prime" it with juice from the top since the juice comes thru the holes at the bottom. Do a lot of research on ss carto replacements. SCV cloud maker replacement cartos were what I found and I will buy when I need a new bath, however they are not pre drilled Darn. Harder for you. But look for something like that write up and research it on ecf for reviews. If you use a thicker juice best go with 2 holes. If you use VG only it will turn in to a hassle basically. Too thick. Three holes to often creates the hard to reverse flooding. Easier and less hassle to drip ( periodically on single hole ) than deal with flooding. I am just lining up 3 clearos to donate to my roommate. I'm done with them but I did spend some time getting used to my tank and replaceable cartos. It has a learning curve that deserves attention because really, with a long life battery you can get a whole lot of convenient vaping done. Initially the first several draws are ideal. I have three going so if I am in hungry vaping staeo f mind I can achieve those initial draws more often. The fact is the carto gets a little dryer and heated so flavor and vaper production wanes. VAriable volt helps dominate the slight differences between the same ohm cartos ( ex: 1.7 ohm is really more like a range from 1.6 to 1.8 generally) and differences in juices and their need for some LR vaping and others a little higher resistance. I don't know if this is too much info. I'd rather have too much than not enough. The two things I hate( and everybody does) is dry burnt tastes and flooding. This is what you will deal with but it can be dealt with effectively. Te leaking is what will happen from flooding. Ot from the tank if you get a recommended one. I recommend Pyrex glass tanks. Must have 510 drip tips for 510 replacement cartos and there are a bunch out there. Personally I have three Pyrex glass tanks by theecig.com He's been in business for over 4 years. His priceson cartos are high but I've never bought one that was a bummer. The clear glass ones exclusively. 2 -6 mil slims and 1 -3 mil. I love the 6 mil slims and the size carto, 45 mm long, is pretty ideal for me. The 3 mil size 35 mm long is more problematic, as expensive as the 45 mm and harder to find and don't last as long and just haven't had the best results for me personally. Anyway. Some ecf posts talk about how delicate the tanks are and it's just not true. They make it sound bad at it really isn't at all unless you are very clumsy and bash things all around and drop on concrete. The other thing about theecig.com is he has along, very slow video perfect for showing how to use the ssreplacment cartos in tanks and wether you up his stuff or not it is Avery good intro to it. It was for me anyway.
That's it. If you have any questions I'm happy to try and share my experience with it. All systems have their limitations, a lot of people try different things and change and then denounce what they used before. Mostly it's good if you learn to work with it. Even clearos. But I love my tanks too much to try and other with clearos myself for the cost factor.long winded. I usually am not. Enjoy. Sorry for any type is I am not going to correct
