I am currently using an aspire bdc for
vaping but find that the flavour isn't what I experienced with my cart on my starter pack.
It had string filaments, no idea what it was called, I had leakage problems with it.
What's the best cart for a good taste?
Welcome to ECF, Suffolkfox...
That would have been some brand/model of TCC or top coil clearomizer. Like anything, there a good ones... and crap.
Not good form to call clearomizers "carts", as there are actual cartomizers (and even sub-categories of cartomizer forms), which are not the same thing as what you started with... but a substantially different form of atomizer.
"Good taste" is so subjective as to make comparisons a near waste of time. It may be that your current atomizer, the Aspire BDC is just fine (quite a popular atty)... and it's your juice, or your voltage that is more at issue.
You may have a fundamental flaw to your
vaping, for which you are not yet fully aware. The best way for people to diagnose your problem and offer sound suggestions is for you to provide more detailed information. Juice brand and blend (PG/VG & nic content), battery type and voltage... and Aspire coil head resistance would be a good place to start. ;-)
