Say one1,
Contrats on your Li'l Sis. I have no idea what resistance carto would be best. That's just too subjective to answer. Monday & Tuesday are my weekend. This weekend I've been using my brandy new C-E2 R(?) from CoV. Got them from Clouds of Vapor a week ago Saturday. Been hittin um pretty heavy ever since. Have reloaded the one I'm using about 8 times. My days off I sorta puff on the Sis pretty constant. Like changing batts bout every 4.5 hours or so. That's just a guesstimate, I haven't really timed how long the batts are lasting. When it quits. . .I just change out the batts.
I think you'll prolly enjoy the Li'l Sister, I sure do.
Cheers,
