Just like the title says... I don't get it. Using an evod twist (vv/vw) protank 2 resistance 1.8 using around 6.5 watts. Anything much higher than that and I get yucky dry hits. UGH! Oh, and cheesecloth wick. I like it for the most part (the cheesecloth). Not much cottony taste to get through when rewicking, and the cost compared to kgd is a whole lot better. I'd like to achieve a more "juicy" vape. Suggestions?
How do you vape at such high wattage?!

High resistance on RDAs 1.2-1.6 duals at 70watts is perfect.
.3 at 70w is unbearable, gross and to hot.
Also air control. The Protank 2 does not have an adjustable air control, so the wattage setting has to be low. And the design of the coil has a very small wick hole, so cranking up the voltage will result in the tank not being able to wick enough juice to keep up with the power setting. My Nautilus Mini with the same resistance 1.8 ohm coil has fairly large wick holes, and air control, so I can take it up to around 10 or 11 watts without the juice tasting burnt. Now with my Subtank Mini, with a 0.5 ohm coil, that will run at 3.6x higher wattage as the Nautilus Mini running the same voltage, and that is purely the result of the differing coil resistance.
Thank you to all so far, but you, jseah, have been most through. I understand everything that has been said, but only so much. Lol I'm still kind of a noob. Only 3 1/2-4 months into vaping. Lol I know enough to be dangerous. So what you all are saying is that I need more airflow, larger wick, and/or lower resistance?
If all you want is to vape at a higher wattage, then really the easiest way to go is to lower the resistance of your coil. Like sonicbomb said, the tanks that I mentioned are newer tanks using newer designs. The larger wick holes helps to allow the juice to flow freer to the coil (and by that vein the most free flow would be dripping directly onto the coil). However, for any coil design there will be an upper limit. For example, take a 1.8 ohm coil. If you want to have a 1.8 ohm coil run at 40 watts, you basically would need to run it 8.5 volts (ohms law: 8.5 volts x 8.5 volts divided by 1.8 ohms = 40.139 watts). You would basically cook the juice since you would most likely burn off the juice faster than the coil can replenish it. Now a wider wick hole will help if you wanted to run at 10 watts rather than 8 watts since the juice will wick easier to the coil.
It seems unlikely that the difference between a nautilus at 10w and a subtank at 36w is solely down to resistance.
The only rational way of making the comparison would be to build 2 coils on the subtank - one of .5 and one of 1.8. Run 36w through each and then report back.
Wattage comparisons between bought coils on different toppers are meaningless - as you say above, there are many factors to consider inc coil design, airflow, juice flow...
The design of the protank is unsuited to higher wattages. This is down to a few factors inc airflow, juice flow and coil design. The nautilus is suited to higher wattages and the subtank higher still.
All other variables being equal, what part does resistance play in all this? This is the best post I have read on this: http://www.e-cigarette-forum.com/fo...ughts-about-sub-ohm-latest-vv-vw-devices.html
The following have a strong influence on your atty's ability to handle power without producing burnt-tasting hits:
- Heat flux. That's wattage divided by the surface area of your coil.
- Wicking and its ability to keep the coil wet.
- Airflow and its ability to transfer vapor and heat away from the coil.
Rayon.
Ohms law doesn't change. If you have a Subtank running a 0.5 ohm coil and you are comparing it to a Subtank running a 1.8 ohm coil, the 0.5 ohm coil will run at a higher wattage than the 1.8 ohm coil at the same voltage. 1.8 ohms is 3.6x higher than 0.5 ohms, so the wattage for the 0.5 ohm coil will be 3.6x higher than the wattage for the 1.8 ohm coil at the same voltage.
1.8 ohm coil at 3 volts:
3 x 3 / 1.8 = 5 watts
0.5 ohm coil at 3 volts:
3 x 3 / 0.5 = 18 watts
Ah. I apologise. I didn't understand where you got the 3.6x from and duly misinterpreted. Hence my 10w/36w remark...
Until just recently, I've been using a Kanger AeroMega with dual coil heads ( @ 1.8 ohms @ 12.5 watts ). I purchased a couple of new toys......an iPV mini v2 ( up to 70 watts ) and a Horizon Arctic sub ohm tank (using .5 ohm coils). I really didn't know what I was missing until now! I run the .5 ohm coil @ 40 watts, and damn......IT'S EXCELLENT! Of course, after 4.5 years of vaping 510's to Ego's, and many others.........NOW is truly a good times to start vaping, with all the advancements/improvements in mods, tanks, coils, etc.!
Thicker wire takes more power to heat up.
your protank2 1.8 ohm coil would be 32 gauge.
a 28 gauge 1.8 ohm coil would need about 8 volts and run at about 20 watts.
Comparing the mini Nautilus to the mini Subtank (or any other subΩ tank) is comparing apples to oranges.
The major limiting factor is going to be the small airhole (even when fully open) on the Nautilus and wicking. Anything higher than ~18 watts is going to give you dry hits.

Someone forgot to tell my Nautilus that.
Even chain vaping taking straight lung hits I get no dry hits at 19 watts.
Thanks again, everyone! I'll have to read over all this and process it again after some sleep. The "Easter bunny" had to get up entirely too early today. 
Please feel, free to continue educating me (and anyone else who may find themselves here). I have a provari and kayfun v4 on their way. I surely want to learn how to use them at their full potential! I am not, however interested in dripping. Too time consuming and inconvenient for me.

You'll notice I said ~18. Try vaping your Nautilus at ranges that the mini Subtank was designed for and you your Nautilus won't keep up.
Not doubting that, but you'll find that the Nautilus coils can take ~25W with the right juice. A lot of variables there, and juice thickness and the amount of coloring in it is at least as important as the airhole size. Run a thin, clear juice through it and you can push the wattage way up on the Nautilus without getting burnt taste. It's going to give you quite the throat hit though.
Consider the difference between a moped and a massive truck. The moped may actually be more fun to drive but when the question is of size, there is only one answer. Every single component of them is different.
This is such an over simplification but is often true. The reason is a reversal: since usually the batteries for both big and small are the same (midpoint) voltage, high power devices will need to have lower resistances. However, that is not true of Protank 2 coils, they're actually avail. in different resistances to accommodate different batteries, airflows, and preference.
