thing is- if you're using 75w with a 0.5ohm coil and wide-open airflow, your flavor WILL be muted, and the heat alone, will lessen your flavor, usually. (this isn't a scientific FACT, and, it isn't going to fit every e-liquid or every palette... but, 4 the most-part, it's true) If you are using a HIGH wattage, like, 100w, then, your vape is going to be VERY warm, and, the flavor usually loses something @ that level. HOWEVER, SOME flavors taste BETTER at HIGH/Ultra-High wattages. Some people prefer coffee/tobacco flavors @ high wattages. SOME people believe fruits simply cannot be tasted to their full potential, past 8-12 watts. So, it's really up-to the person. This is certainly an old wives tale, though, considering, you ARE going to TASTE your juice's flavor at high wattages/with huge plumes of vapor, in-fact, a-lot of the time, the flavor will be incredible at high wattages. Simple as that.
Like I said, I do prefer a lot of flavors at lower wattages, though... & I DO feel that a lot of flavors lessen at ultra-high wattages. I do agree with the poster whom has issue with those whom say things like "You cannot chuck plume at lower watts/higher resistances" lol. BS! I mean, when I open a brand-new Ego-ONE coil at 1ohm, and I vape that baby at 12.5 watts, i get HUGE, HUUGE plumes of vapor! So, I can shenanigans on any1 whom believes you MUST utilize sub-ohms and ultra-high-wattages to chuck plumage. BS! simply BS!
HOWEVER- You're most-likely going to have a MUCH easier time, chuckin' some vapor, at HIGHER wattages, regardless of your coil. Right? The coil doesn't matter, the WATTAGE does... You can have a 2.5ohm coil, doesn't-matter, if you vape that 2.5ohm coil at 40 watts, you're GOING to chuck a huge amount of vapor.... If you vape that same coil at 80w, you'll chuck even MOAR vapor. Vape that 2.5ohm coil at 100 or 200 watts with WIDE OPEN AIRFLOW (low nicotine strength, hopefully, lol) you'll have competition size cloudz.... HOWEVER..... Vape that SAME 2.5ohm coil on a mechanical mod, FRESH off the charger, and you'll see, you'll have sum HUGE plumage!! So- The RES don't matter as much as the wattage, and guess what? If your juice is 100% VG in a well-working RDA, hell, yer gon' git some COMPETITION sized clouds with your average mechanical tube mod, with a battery fresh off the charger. (providing 35-40watts) If you DONT have the right airflow, yer sh&t will burn, and, you WONT be chuxkin clowedz....

IF you use a CE4 clearomizer, at 150w, you're most-likely NOT gonna be chuzkin cloods... considering, that lil' CE4 wont keep-up, n it's gon' burn! IF you dunno how to build for mechs, it's gonna be a tooty-poofer build/set-up. IF you have 100% PG juice, tootie-poofing 101... so... DO NOT buy-into the wive's tales..... FLAVOR, is subjective to each tongue, and, plumage, well, it depends on your build, but it also depends on whether or not you've got a good mod, and the RIGHT wattage...
