well I just switched to 100% vg RY4 from evcigarettes, it's the best juice I have ever tasted. Coils don't last as long but I get protank coils
from discountvapors ( 5 pack) for $6. The best delivery system for me though is the iclear 30's and replacement coils for them from fasttech are $6 for 5 (shipping is a little slow so I stock up when I order) With coils being so cheap if I get a day or two out of one I am good, I wouldn't vape something I liked less to get an xtra .15 cents worth out of one. Thats just my 2 cents worth
