Ok, here's my full take on this.

I've been mixing for 3-4 years, I'm a juice vendor, I started mixing when I was on a Protank/MVP combo.

I've only had to rework recipes the other direction (MTL->DTL) because there were things in the juice I just wasn't picking up on in my MTL devices (I peaked MTL on a Kayfun 3, I think).

For instance, I have a kiwi strawberry that was one of my first recipes. In a Protank using a microcoil/cotton rebuilt head it was good. In the Kayfun it was better. In an RDA with good airflow using a twisted kanthal coil riding a mech there was a weird rancid note. I tried all three devices side by side for a couple of days and in every test the RDA got me that rancid note.

I backed down the flavor percentage and it went away, didn't notice any change in the MTL devices other than maybe a slight muting of flavor (maybe?), but on the RDA it was like someone turned the flavor to 11.

That said, I have found that increasing overall flavor percentage of juices for MTL devices can give more flavor on the MTL device (just be aware of issues that causes with DTL setups like I just talked about).

This is (I believe) due to the differences in how these devices are delivering vapor. This is especially true with something like fused claptons in an RDA.

You're simply going to be able to pick up on flavor notes with something like a dual claptoned derringer that you'll never taste in even a Kayfun 5 (which I have and love), no matter what you do to the juice.

While PG carries flavor better than VG in most cases, it's not enough to compensate for the loss of flavor production when moving from DTL to MTL devices, if you are capable of detecting the changes.

The biggest issue with a question like this is that taste is subjective. And not just "I hate orange vapes" subjective, every person tastes differently, and any two people may not even be capable of pulling the same notes out of a given juice, even using the exact same device.

In my experience, if it tastes good in a MTL tank, it will taste spectacular on a DTL RDA, with exceptions (as noted above), and depending entirely on specific devices and individual tastes.

I develop my flavors on a derringer with dual SS316L 28/36 fused claptons. In my experience, this is the absolute most flavor I can get out of a juice.

The increased surface area combined with the varying temperatures found in a fused Clapton just works to produce more flavor.

I then test across an array of devices (including MTL) to see what I get out of that juice on different devices and different settings/coil materials.

Occasionally I'll find something that tastes off or weird on a given device and that requires that I make changes, so I make the change I think will correct it, and start the whole process over again.

It can get maddening, and sometimes there are just trade offs that need to be made. You can spend months chasing the dragon of that perfect juice that tastes perfect in every device. While that juice may exist, I've never found it.

If you're mixing for a specific device, it becomes much simpler, as you only have that one device to test on.

The only real rule of thumb I can offer is that flavor is going to be less on a MTL setup that on something that is designed for maximum flavor delivery like my derringer setup.

You can try to counter that by making adjustments where you find deficiencies, but just don't expect to get the exact same level of flavor from a MTL setup.

Hope that kinda points you in the right direction!

Have you tried just changing the PG/VG ratio and nic?

Most recipes are pretty flexible on the device end.

As mentioned if anything you'd need to up flavor percentage on some recipes.

In my experience it's pretty rare that you'll taste something more intensely on a MTL device than in an RDA.

Honestly, I'm a MTL high mg vaper through and through and I never feel the need to adjust flavor percentages to make up for the ratio, nic, lack of vapor, or anything. It all translates pretty well, though there are a few exceptions as stated before. I have been mixing a little over a year now, lurk here constantly, mix up a lot of recipes posted here, and tend to stay within recommended percentages 99% of the time. I hardly (if ever) feel the need to compensate in either way because I'm mixing for MTL. Hope that helps!

I might be wrong but in case no one else comments (and they will if I'm wrong!): I think you would actually need to bump up the flavor percentage IF it needs to be changed at all.

If I were to experiment I'd make a 10ml batch following the recipe and a 10ml batch with everything bumped up by the same percentage.

I don't mean add 10% to every ingredient but add 10% of the percentage.

So tfa vanilla custard 5% is not going to be 15% but 5.5%

5+(5x0.1)=5.5

Original percentage + (original percentage x increase in decimal)

IF you have to lower the flavor amount do the same thing but subtract instead of add.

There may be some long-time mixers around that were doing juice back in the days of 50/50 and 18mg! Not like it was so long ago like in the days of Disco!

But I think you may need to increase the flavoring percentages due to vaporizing so much less juice with each hit. Less power, less heat, less airflow = Less Vapor.

Less Vapor = Less Flavor Molecules per hit.

I could be wrong... hopefully a true veteran mixer will weigh in.

Do you feel like you're not getting enough flavor doing it the way you described, just increasing PG and nic? If so try increasing percentages across the board, evenly. Multiply each flavor percentage by 1.2 and try it that way, see what happens. If you have a good MTL device I wouldnt think you'd have to change anything.

• Just mix the recipe
• break out the Kayfun, Protank or Nautilus and taste it
• adjust V2 to taste
• repeat
