most likely you will find it much better to get new atty... i'd try a 1.8 to 2.0 LR, as they won't get as hot at the 1.5 Ohm.
I will experiment some when I place a new order. I ordered four of the 1.5s from Vapage with my orig order, so I still have a few of those to go through. I always am trying to get more throat hit, even when I was using the Boge 2.0s, which is why I thought I would like the 1.5ohms from Vapage. The problem is when something tastes off I sometimes can't tell if it is user error (flooded/dry atty, low battery, etc), hardware error (bad atty, etc) or if everything is working perfect and a certain juice just tastes gross above a certain wattage, when there are so many variables at play simultaneously.
The good news is it seems like I have got the atty going again. Last night I gave it a long dry burn session, then soaked it in alcohol for a half hour or so, rinsed it out with water, and let it fan dry. Btw, I may have "invented" a new way to expedite atty/carto drying last night! Anybody else do this?
Either way, it seems to be working today. For me to get a good, tasty vape, the atty needs enough juice in it to give it a slight gurgle, which makes me wonder if something is still not right, or if it is just a byproduct of needing enough juice to keep up with that amount of heat. Anything less and I start to get that burnt-hair taste.
