If I was looking for new I'd pass on these too. I'm fine with the standard drip tips. Just eyeballing the one in use now, without using a mic on it, I'd guess the bore is about 3mm at its narrowest point. And it IS the narrowest constriction which determines airflow.Agreed. Wide bore "chuff" tips that can't be changed out are a deal breaker for me.
If these are being used for actually dripping, it makes a degree of sense. I used to use the ego-type Mega cylinder type B atomizers for dripping. And their drip tips had a larger than average bore, for the time. But since they were literally 'drip' tips, it made sense. They weren't as big as the ones pictured at the top of the thread though. It must be a style thang. One I don't care for. But, to each their own.
I've been vaping for nearly seven years, but I smoked cigarettes for 35 years before that. My cigarettes had a draw which was NOT like sucking air through a straw.
