I have a few evods and mini pro tank2s. I like to vape around 7 watts and was wondering if there is a difference using say a 1.8 at 3.6volts or a 2.7 at 4.4 volts both being a similar wattage.
low ohm vs high ohm in evod and pt2?

You know, the difference is taste and the way, YOU, will like it. To throw a 3rd scenario out there, I like my coils around 2.2 ohms.
Give each a try, and see how you like each one. Only use Kanger heads, and save the ones that go bad. Rinse them off and throw them in a tin. Down the road, you will want to try your hand at rebuilding them. It can save you a lot of money.

thanks. that's what I use. been trying different resistant coils and since I've had vapers tongue for most of my month of vaping I can't tell the difference. still good and got me off analogs. I've also been cleaning and dry burning them and trying 2.5 silica wick material. that's been working well. I don't think I have the dexterity to rebuild those tiny coils so if I can get a couple runs with them I'm good.
I find that for most practical purposes, 1.8 vapes the best. Doesn't deplete batteries so much like 1.5 and heats up faster than 2.1/2.2 ohm heads. My resistance of choice.
I was actually surprised that I COULD tell the difference.
I figured with a VW mod I would no longer care whether I used a 1.8 or a 2.4 - but I found I could tell the difference, and have a preference for the performance with lower resistance. 1.9 or 2.0 is about my "sweet spot" - for MOST juice...
Try both, and yes - as the previous post said, I'll agree the best results will probably be if you get into rebuilding just the way you want (though personally, it's not "my thing" - and I buy 'em).

I have the iTaste VV 3 and only use Evods or my ProTank Mini's and I find 8 watts gives me the same taste whether I'm using 1.8 to 2.5 ohm coils.
The main reason for having a Variable Voltage or Watts. You start lower, work your way up, and when you find the right Voltage or Watts, you stop. Using higher Voltage or Watts, does not mean better taste.

Ditto with the eVic and Protank Minis and ProTank 1s--can't taste a difference from 7-8 watts.
It's all individual and subjective. Whatever works for you is best. Some can taste differences at different resistances and same watts, some can't. Some people can taste the filler in a carto, while I can't (what a tragedy). To each their own. About the only difference is resistances that important from a numbers standpoint is that the lower the ohms, the more current required, and the shorter the battery life. High resistance, longer battery life. Low resistance, shorter battery life. Can't remember, though, when battery life made any real difference to me. I'm battery rich, and replace as required, without a second's thought. Good luck. Do what works best for you. My two cents.
I find that burnt taste has several legs, I'll try to explain:
How you break in your coil: Depending on what you use, breaking in your coil extends its lifespan. For BCC in general I wash a new head prior to use. Machining liquid can be left behind and it's the culprit for burnt taste.
Liquid density: the more dense the liquid, the harder is to feed into your coil. For bottom coils means removing wicks until you find it keeps up. To prevent flooding, don't remove all at once.
Voltage: When you first start using a new coil, start low. Some coils produce great amounts of vapor with only 3.3V. If you see it wicks well, rise your voltage slowly as you vape along. Most typically, it'll start breaking in at about 2.5 ml vaped.
Head resistance: If your resistance is too low, you could be running at a very high voltage. Check your resistance and calculate it's not going over the top. http://www.ohmslawcalculator.com/ohms_law_calculator.php
PWM: Some devices get to the desired voltage by pulse width modulation. That means that it will cycle from the highest to lowest voltages at a certain amount of cycles to get you your desired voltage. It could also mean you're frying your coil. Certain mods should be used only with regular resistance clearos.
Fusion point of eliquid: Certain components of eliquids don't whitstand high voltages. If you've checked all of the above and are right, the culprit could be some component of your eliquid.
Hope this sheds some light...

For a given coil wattage setting on a VW mod, coil resistance doesn't impact battery capacity usage. The VW mod will decrease the coil voltage with a lower ohm coil and increase the coil voltage with a higher ohm coil, to keep the coil wattage constant. Voltage isn't free--the higher the voltage, the more current drawn from the battery to produce that voltage. With Pulse Width Modulation, the duty cycle conducting time increases as coil voltage increases. The principle of the conservation of energy applies here. If it's 8 watts to the coil, it's 8 watts [plus a tiny bit lost in the circuitry inefficiency] coming out of the battery, regardless of the coil resistance.
