Lots of truth to that, Burnie.
You can also check the voltage on the 901, and resistance of whatever topper you use on it, then calculate the watts consumed by that setup, then set the VV wattage to match, so it will automatically adjust to that value.
I find that many of my flavors will have their particular "sweet spot" for vaping, and they're not all the same. Maybe you're just vaping at a totally different power level...
Thanks guys. Looks like it's time to dust off the old multimeter.
