I just bought some e-liquid from a couple vendors, wanted to get a 100% VG blend instead of the PG blend. What I noticed was that the VG blend tends to clog up my cartomizers. Another was that it would take a while for me to get the taste, as if it would be muted for about 5 mins then come back a little. Don't get me wrong though, the vapor production I'm getting are really good clouds, but the cost of getting a really hard draw from it sometimes. For future reference what's a good PG/VG mix? and I really don't want to throw away my cartos just yet, but I can still clean them right? I have a KR808D1 model.
