Micro coil question

[degnr8]

I'm an rba newbie (currently running an A7 @1.3 ohm with 32ga kanthal and cotton wicks if it matters) and I wanted to make sure I understand the advantage of microcoils before I buy more wire. If I use a thicker wire with more wraps I'll get more heat at the same resistance or the same heat at higher resistance because of the greater surface area, is this right? I understand that low resistance creates a higher drain on the batteries as well, so does this mean if I was able to get the effect I'm after at a higher resistance that my batteries would last longer?? Also, what about ribbon wire, does that just produce a larger surface area for the same gauge?

For me , I run two different micro setups, both are just under 1/16" inside diameter. First is a 30 ga with about 12 wraps to get 2 ish ohms. It is the perfect Marlboro light style vape for me. I currently have that build on a VV but also ran it on mechs with the same satisfaction. I keep my VV at nearly the lowest power setting.

Next is the 27 ga with around 10 wraps to get around 1 ohm. This setup is killer in that if you fire and hit right away (my drags are about 3 seconds) it is nearly the same vape as the 30 ga 2 ohm. However, if you fire for about 3 seconds before hitting, you bring out the full fury of the 27 ga because it has fully heated up and the vape (to me) resembles a hot boxed Marlboro red. Getting two distinctly different vapes from one build = priceless


Edit: ribbon? Tried it and gave it away. The capabilities of round wire in a micro configuration are more than adequate and easier to work with.

So, ohm for ohm thicker wire equals hotter vape then?

So, ohm for ohm thicker wire equals hotter vape then?

I'm thinking that wire thickness isn't as important as resistance. I believe a 1 ohm micro coil is gonna be hot (or be the same heat) regardless of wire thickness. The difference is gonna be reaction time and remember, More wraps = better vape so a thicker wire (27 ga in my case) is gonna perform better at SLR because it allows more wraps.

Since it is thicker it has a slower reaction time and it takes longer to heat up, the initial 3 seconds (while it is still heating up) vape similarly to a 2 ohm 30 ga that heats up right away.

With micros the thicker wire is best suited to SLR and the thinner stuff to LR / SR.

To throw in more variables, here's my latest variety where one side heats slower than the other adding a little dimension to the vape when fired and hit right away:
