Tube type vv/vw units

First off I'm a newbie. Been vaping for 2 months now after smoking for 18yrs, and I gotta say I love it. My first ever setup is a segelei 30w with an EhPro kayfun lite. Loving it except for the odd time it floods on me. So I guess my question would be, I'm looking for another tube type vv/vw mod with the same or greater wattage capabilities. Anybody try a bec pro 50w, or a greenleaf 30w? My sigelei has seen better days and not too trusting in it after the top came apart. Debating buying another sigelei, but be more cautious with it. My typical coil build is between 1-1.5 ohms on the kayfun. I also have tried a couple mech mods and I'm not impressed with them. (Then again not very knowledgable about how they work). They don't hit like the segelei does with the same coils. I have a smok magneto and an aspire cf mod. I also have an Atlantis and a ud igo w-4 rda with a .8ohm coil setup. Any advice would be great. Looking for throat hit and flavour more than clouds although it seems to be somewhat combined.
 
If I put the kayfun lite on one of my mech mods I don't get the vapor that I do on the segelei. So in my short experience the mod makes a big difference, Correct me if I'm wrong. I'm not a fan of the dripper I have due to airflow or lack thereof, but I get lots of flavour and good throat hit from my kayfun so I'm sticking with that. The Atlantis I just got 2 days ago and still on the fence about that one. Just wanna replace my mod with a simailar unit due to it falling apart. Would prefer to stay with a tube type and vv/vw 30w or better.

The power a system draws and therefore how hard it hits (if you want more) depends mostly on watts: volts by amps. So the reason why your mechmod does not hit as hard as your VV tubemod is because you have almost certainly raised the system voltage to higher than the normal battery level on VV, and therefore increased the watts generated (the measure of power). You are probably running your ~1.25 ohm kayfun coil at about 5 volts or near it, on the sigelei VV. You get about the same (theoretical) effect by dropping the coil resistance to around 0.8 ohms at 4 volts on the mechmod. If you can't raise the voltage then you drop the coil resistance instead.

So to get the same hit, you can either raise system voltage or drop coil resistance, the theoretical result is the same (the power draw). However, theory is not practice, and in the real world there are few direct equivalents: either something has to be varied slightly from the mathematical equivalent; or because of the characteristics of the refill liquid, exactly the same result is not achievable since multiple factors have changed and the refill behaves slightly differently - it doesn't taste the same even at exactly the same power draw. The hit is going to be about the same but the taste may be different.

Some prefer raising the voltage using VV, because that combination of volts/amps/head/coil/refill suits their taste perfectly.

Others prefer using straight battery voltage and dropping the head resistance, because that combination of volts/amps/head/coil/refill suits their taste perfectly.

It's whatever floats your boat. The maths might look identical but the taste usually isn't, and that's what counts. Also, many people find that taste can change over time. Next year you may have an entirely different opinion.
 
Thanks rolygate, that makes sense. I've not had anyone to explain all this to me before. A few vape shops I visited told me lower ohm on mech mod would make a better hit. But didn't explain why my segelei was hitting better. Increased voltage makes sense now. The segelei increases the volts automaticly so I didn't even notice it. I can only adjust watts. Thanks again.
