I have been experimenting with builds for my Toptank RBA. I usually go with 28g kanthal with 8 wraps and a 2.5mm diameter. That leaves lots of room for cotton to fill in the gap. I just tried using 26g kanthal again with 8 wraps and 2.5mm diameter and have more coil mass, and less room for cotton.
I'm trying to get the best build for flavor and not really noticing a difference yet. Is more coil mass better for flavor? Does it matter?
Anywho... Does anyone have a favorite build they like best?
In contrast to my Kayfun V4 my Russian 91% seems flavourless. I'm not sure if more coil means more flavour, YMMV !.
It doesn't matter how much coil i use in my Kayfun it still produces a great flavour. These days i am using 29g kanthal, 5 wraps, 2mm I.D equalling 1.0 ohm. At 11.5 watts - 3.4v this 1 ohm coil ticks all the right boxes.
I D.I.Y my own 24mg juice 40ml at a time with 13.3 ml of 72mg (50%pg/50%vg) nicotine liquid, 0.6ml Capella Coconut and 1.8ml of Capella Choc Fudge Brownee and the other 24.3ml is plain Vegetable Glycerine. Even with just this amount of flavouring (2.4ml) my Kayfun still produces great flavour and i still might reduce it even further yet.
Incidentally this concoction of flavours unsweetened is as close as i can get (so far) to the burning tobacco taste i used to get smoking "Old Holborn". Still thinking about adding another flavour or two but just haven't decided what, and this is one of the reasons for reducing the overall % of flavour at this stage (Old Holborn simply doesn't have a great deal of flavour) so less is more when it comes to trying to synthesize an authentic tasting e liquid which tastes the same as burning Old Holborn tobacco.
More flavour % doesn't mean a better e liquid in this case !.
Anyone will tell you that the taste of burning tobacco cannot be produced in an e liquid.
Difference with Old Holborn is it does actually have a very individual/unique taste, unlike any other tobacco "i've" ever smoked at least !, a kind of sublime sweetness.
The conbination of Coconut and chocolate in my D.I.Y juice with only the sweetness of the Vegetable Glycerine added isn't a million miles from the flavour of burning Old Holborn, but there is something missing !, just a little something to take away the slightly bitter chocolate taste. I though about one or two flavours i could try and will eventually get round to it.
Initially my first thoughts were to reduce the overall % of flavouring, so i went from 3ml of Choc Fudge Brownee / 1ml of Coconut, to 2.4ml / 0.8ml then even further still to 1.8 / 0.6 which is where i'm at now (notice the ratios are still the same - 3 quarters of 1 and 1 quarter of the other). It has improved, with a less pronounced chocolate flavour, (obviously, fundamentally less flavour !).
Like i said earlier, finding an e liquid which tastes the same as the typical taste of burning tobacco is not going to happen.
"Old Holborn" is different. It does not have that typical burning tobacco taste, far from it !.
This D.I.Y flavour is a work in progress. I'd say, subjectively, that it's about 80%-90% complete, and just a tiny little tweak needed with another flavour added to drown out the bitter chocolate whilst retaining the "apparent" smokey flavour being produced through the combination of Chocolate and Coconut, (don't ask me how that's happening !).
I doubt anyone would appreciate this flavour. Seems anyone who vapes is looking for flavours which taste great.
All i've ever wanted was to vape something that tastes the same as the tobacco i used to smoke.
It isn't too much to ask. And seems to be the only thing missing from the vaping industry. Strangely enough no one seems to care one way or the other. Well, no one except me !.
