As you are asking about cartos..... I have several native 801 REOs (7 Woods) and many more 510s. DH and I had been confirmed atty users since Aug 2010. I do, though, have 801 Fusion cartos from IKV that I do use. A few months ago DH and I both started using CCV Resurector Cartos on our 510 REOs. For
our flavor juices, they give the best flavor of any carto I've tried/used, including just about any atty/carto available in the US.
So after trying the Boge 2.0 and the Resurectors 1.7-8 we quickly settled into the Resurectors, as giving the best all round 510 carto vape. I love the IKV LR attys, and for over a year, had mostly used the 801 attys on my native 801 REOs. So, after falling in love with the Resurectors cartos I decided to put a Fusion on one of my 801 native REOs to compare.
Great, but not nearly the flavor that the 510 Resurectors give for
our juice. So my recommendation, if you have a native 510 connection, and want to use cartos, is to go with the CCV Resurectors or the Boge cartos.

{edit} Our main flavors are FSUSA 50/50 Applewood, Hopscotch, Butterscotch Almond and a few 100% VG juices. If the juices are 100% and, if a little thick, we thin, a bit, with distilled water or PGA.
