i used to be the same - way preferred to drip. then i had to start squonking out of necessity and now it's become easy peasy. once you start you'll get the hang of the levels with trial and error (quite a bit of error).
the taste/feel is slightly different and it baffles me too, but i'll take that for convenience sake.
one thing about juice levels: i can't overstate how important trial and error is. the rule of thumb you'll also see in other threads is waiting for the juice to just peep through in the well and then releasing, and then sucking the juice (without firing the atty) a little bit (one or two small pulls? doesn't have to be too hard). sometimes when i've accidentally over-squonked and i see a bit more juice in the well, i won't dry pull because then i might flood the atty - i'll just vape a bit and then suck the excess juice from the well into the atty after a few drags. trial and error.
