The amount of wattage applied to a flavor can change it significantly. You may be kind of stuck in a bad place with your (very) sub0hm coil, and balancing the amount of wattage you need to get decent vapor production versus a more subtle or less flavored juice in the tank.
If you like it in your MTL setup why not save it for that? Sub0hmers will (sometimes, especially if high wattage) ask for extra flavor in their juices, due to the fact that the type of sub0hming you are at can result in some flavor loss (why, I have no idea other than the amount of vapor being produced can be overwhelming, or merely running at higher wattages may require more flavorful juice.
You can continue to experiment, certainly, but I might consider experimenting with other (and perhaps more strongly flavored) juices. If I were vaping an e-liquid MTL, I'd probably also want to get a lower nicotine setup as well (and possibly on the higher VG side) since if your vapor production rises, you will be getting far more nicotine per puff than on a small, MTL device.
Best of luck as you experiment!
