I'm bookmarking this thread. Great coil building resources are linked throughout. Thanks to y'all who did that.
(And I'm a Rip Trippers fan, anyway.)
But I'm moving more and more towards CannibalGirl's position on the matter of building. I've only built one coil so far. It was for a Kayfun 3.1. A large tank, and a large coil deck to work with. I want to try - just once - building a coil for my beloved PT3. I think after I do that, I'll probably never want to do it again.
I've always been a very tech savvy person. I disassembled and reassembled my toys starting at age 4, and even the more complex ones never gave me a problem. I'd often find ways to make them better, in fact. But building a coil for vaping is simply below my minimum scale threshold. I felt like I was trying to join electrons when I built my KF coil. And that was a larger platform. The work is just too small for me.
I'm sure it's largely because I've lost the very sharp eyesight I've had throughout my life. I have to wear 1.50x glasses for "normal" existence - TV viewing, reading medium-sized text, cooking, etc. I have to go up to 2.00x ones for any small work. And I have to couple using my 2.00x glasses with using my big, armature-mounted magnifying glass to do
really small work. It's just not fun when I am at the lower limit of my ability to see and handle something.
I can rebuild a mean engine. I can install a cold air intake, and underdrive pulleys, and high-flow fuel injectors and a low resistance exhaust system and get great results from it all, and enjoy doing it all as well. Because those items are larger than ten electrons wide. Building coils isn't. (Yes, I'm exaggerating, but y'all get my drift, I think.)
I'm 6'4" and I have big hands. I don't enjoy doing little work. And I hate that I don't enjoy it. I think building your own coils is smart and efficient and thrifty. And yet I just won't like doing it, I'm pretty certain. I'll try it once or twice more, but unless it grows on me in a big way (no pun intended), I'll just buy my coils from now on, and at some point, I'll have to just lay down my Kayfun. As much as that will break my heart.
I can't buy coils for my Kayfun. But I can get my PT3 coils for under $2 each. I'm fine with that. A PT3 coil lasts me over a week. I use about $5 worth of electric juice per week. Under $7 per week as my expenditure to vape is an amount that I will never complain about. Not even once. Compared to the $43 per week I spent on cigarettes? Under $7 per week. I'll never complain.
And if, at any time in the future, I fear the FDA will be banning the sale of replaceable coils, and the use of wire and cotton by Americans, then I will quickly hoard as many replacement coils as possible for my PT3, Nautilus, Aerotank or any other changeable coil device I'll ever have. And I'll hoard cartos for my cartotanks as well.
To answer the OP, I actually LOVE my Protank 3. I love it. It's my current favorite tank. I like the flavor I get, I like the vapor I get, I like the amount of electric juice it holds, I like its method of refilling, I like it's method of coil replacement ... everything.
But I
do get more flavor from a cartotank, just as Tinkiegrrl says. And, as such, I love my SmokTech DCT. I'm going to get a better cartotank solution at some point. I love the flavor kick I get from cartotanks. The catches are that they're harder to fill, harder to replace the coil (i.e., carto) and they can be messy for a semi-klutz like me. So they're not my favorite vapor delivery device. When considering all the factors, I still prefer the PT3. But I will still buy and use cartotanks because they fill a niche in my vaping that's important to me. One that my PT3 doesn't fill.
Regarding the Nautilus and the Aerotank - I haven't tried either yet, but I'm going to buy one of each because I've heard about an equal number of ECFers tout each of them. I bet they're both great clearos, and it's probably a matter of discreet design or functional preference that steers a person more towards one or the other. Maybe I'll like the Nautilus capacity and coils better, but maybe I'll prefer the fill method and airflow control of the Aerotank better. Who knows until I get into each one.
I just doubt you could buy either of them and end up hating it.
