Well, you ARE using a lot of PG, and that Kanger taste is sort of PG-like, industrial, and it won't go away. I mentioned him because Pete Busardo is considered a very experienced vaper with a big following, and he too finds the Boges cleanest-tasting and the Kangers not. Maybe you hate VG, and Boges taste VG-like? Who cares, to each his own, whatever you prefer. I like the taste of CE2s, and EMDCCs, but neither makes much sense on the Vmods.
Yeah, so far, a 1.5 ohm HH.357 is indeed hard to beat. Before I realized they need a juiced-up rest, I'd switch to a fresh Boge or Resurrector, tearing up the o-ring in the process, vaped happy for 2-3 days until it started getting mungy, tossed the carto, put the HH.357 back on and totally wondered why I switched in the first place. Now I just oversquirsh the .357, let it sit vertical an hour, and ... he's baaaack!
Gotta make sure liquid gets all the way up and covers the coil before it pulls back, that's how to avoid the nasty dry hit. Gotta make sure the tide pulls fully back, like sand on the beach, to avoid El Gurglito.
There's a technique I haven't fully mastered yet, of vaping the .357 with the Vmod slightly tilted, suck hard, and then it almost just feeds itself, no gurgling, very smooth.
Drat my second blue vapage battery just died. First one reads 2.9 mostly, this one 0.0000 v.
