I think that's defo the issue if you're vaping juice that is very light with no sugar your coils will last but if not no!!
Coils will last with proper maintenance.
Charlie there are many many flavors made by all the flavor houses that have sweetness already in them. Everyone doing DIY uses them all the time. The creams and custards that you use have sweetness in them. Strawberries have sweetness... on and on the list goes.
My motto has always been... learn and know thy flavors. And know what they can bring to any mix at different %'s from very low (as in drops) on up.
BTW, EM (ethyl maltol) is not in all sweeteners. There are different kinds of sweeteners that use different ingredients. If you look up DIY sweeteners you will see for yourself which ones use what as their main ingredient.
This may be of interest...
In the nearly 9 years that I've been doing DIY I have rarely used a sweetener. In fact, the last several years I've used no sweeteners at all. I know how to bring sweetness to a mix, if desired, using the flavors in my stash.
If you truly know your flavors, then you automatically know there are always flavor options available to you for adding sweetness to any recipe without the addition of a sweetener. And it doesn't require much of a flavor, or two, to do so. If properly mixed you won't even notice those flavors, when used as
additives.
There are numerous flavors that will bring sweetness to a mix, round out other flavors and reduce sharp notes in 'certain' other flavors.
Likewise, there are flavors that will reduce sweetness in a mix.
It
always comes back to how well you know the flavors in your stash.
The way I see a lot of folks using sweeteners...
IMHO...is a band aid (some will bristle at that, oh well

). Too many people use them as a crutch to cover up crappy recipes.
ELR, and similar sites, are littered with those kinds of mixes. And that comes right back to folks not knowing their flavors, as they should.
Having said all that...^^^...sweeteners can be a tool...if used properly.
Matthew Topolski lead mixologist, Head of R&D for Charlie Noble, Walker Trading Co -Vape Dojo, Tenbuck & more --- and also contributes much to the DIY community, says the following of EM and it is true of any sweetener.
"Cotton Candy/Ethyl Maltol – this is not here for sweetness! Please, can we all just take a minute and set down the EM and sucralose? If you need to add multiple percentages of a sweetener, then you need to revise that recipe. Ok, done preaching. EM is amazing when used for its real purpose – rounding off rough edges. It can make flavors layer together, or can make that one sharp accent drop down a notch or two. Half a percent is just about perfect for that purpose."
I've had several good convos with him over the years and also learned a lot from him. He's very sharp with everything DIY. And very approachable and helpful with DIY questions.
