It's all about watts when using the same gauge wire, otherwise with say heavier wire ramp up will be longer as well as cool down.

Well kinda. If you are talking about the same fixed voltage to the coil like in a mech mod, then yes. But if you can vary the coil voltage like in a regulated mod, then you can adjust the voltage to where they produce the same vapor. And if the surface area of two coils are the same and the wattage is the same, coil resistance really doesn't matter.
A purest would say there is more factors like heat flux, heat capacity, power dissipated, etc. But that is getting nitpicky and we don't necessarily need that kind of accuracy for here.
- 1Ω, 5V @ 5A = 25W
- 0.1Ω, 1.58V @ 15.81A = 25W
Trying to wrap my head around this. I get the theory behind it- but how does that relate to my experience of:
I put a 1 ohm build in a KF- I get what I enjoy as far as a vape- at 15W.
I put a .4 ohm build (same wire-coil built to lower resistance, same tank, same regulated device) 15 W yields very little vapor, if any. Need to jump it up to maybe 25 W. But then I get dry hits. So how is wicking not affected by the lowered resistance (which requires higher wattage for same vape)?
Or to put it in another way- using a regulated mod- a KF should be able to fire a coil at .1 ohm, with no dry hits but with an 'acceptable' vape (if resistance doesn't matter on a regulated mod)?
There is more to it than that...
Which Kayfun?
What are the specs of the 1 ohm and 0.4 ohm coils?
It's possible that the specific Kayfun you are using can't keep up feeding the juice demand of the 25W build.
So it's not really the wicking of your build that is affected by the lower coil resistance but limitations on the atty design itself to feed juice fast enough. I could put a 0.1 ohm coil in my Kayfun V4 and vape it at 25W quite easily, but I could not do the same thing on my Kayfun Lite+ or Kayfun Mini V3, those tanks just can't keep up feeding juice.
The resistance not mattering on a regulated mod is totally different than an atty not being able to feed juice quickly enough.
Let me try to put this into perspective.
Lets say we have a Kanthal coil made from 28 guage Kanthal coming out at 1.1 ohm and firing at 25 watts and compare that to a Ni200 coil that is physically identical coming out at .0.073 ohms. These two coils will for the most part vape exactly the same and have the same battery life.
The Kanthal coil will require 4.76 amps at 5.24 volts and the Nickle coil will require 18.5 amp at 1.35 volts. Sure the Ni200 requires more amperage but at less voltage so the battery drain is the same with the regulated board. There are a few small factors not included here like board efficiency but are small.

BBV is outta stock and it would cost me almost 30 bucks after shipping to get that exact one, either from them or the outfit in Canada. For some reason, SXK went silent on me about this switch.
I wound up ordering another Gold BB from Legend, which cost about the same as 3 of these switches and figured I'd work out the switch situation on the other one later.
If this one works, that would be jist peechy keen. I can use the broken switch as a template to fit another one.
I noticed on another forum a few days ago you posted these FT switches didn't work out due to being too thick...
Another option, I was just flicking through a BB Fakebook group and found these screenshots that were posted back in 2017:
These are the switches on ebay:

If you search ebay for "Matrix Array 1 Key Slim Membrane Switch" you'll find a few sellers...
Goodluck

Well,that sucks haha.I ordered 1 of those switches from Ft a few days after you did,so now i have a useless switch on the way haha,at least it was only a couple bucks.Now i'll be ordering a few of those that were just posted since they are confirmed to fit.I don't have any switch issues yet,but it'll be nice to be prepared,and not have to pay that crazy shipping for the ones from Canada.Yes, I intended to report back on this here. Thank you very much for this tip
@TrollDragon "The resistance not mattering on a regulated mod is totally different than an atty not being able to feed juice quickly enough."
I agree. My initial questions was- 'can an Exocet or an Vape Shell feed juice quickly enough'? WHat are their limits. if any? I do not care about batteries or anything else.

Sorry, I misunderstood what you were asking.
I'll be grabbing a few as well. I got ahold of the guy in the screenshots and he told me that the fasttech switches actually last longer than the BBV ones.
Now,if we could find a cheap replacement for the up/down button panel it would all be good,although those buttons don't get anywhere near as much use as the power button,so they may never need replacing,but still wouldn't mind having a few spares for just in case.
I believe you need an adapter like what is shown here:
$11.69 Authentic Vaporesso Ceramic EUC Coil Head (10-Pack) - 316L stainless steel / 0.5ohm(25-35W) / w/ sleeve at FastTech - Worldwide Free Shipping
But supply seems to have dried up, I haven't been able to find one anywhere.. (at an affordable price)
