The key to learning how to drip is to not get all frustrated & mad when things don't go as planned. We've all been there, it's just part of the learning curve. So just expect the dry hits, flooding the atty, and maybe even popping an atty or two. Right now you are at step one of the ten point curve, so forget about all the cleaning stuff, and work on the filling it part.
2.1 ohm will work just fine, matter of fact I have a 2.1 ohm coil in the RDA that I'm using. hint: Joyeteck designed that atomizer for use on their Joyetech batteries, so don't be surprised when it works best at a fairly low voltage.
When that atty is all nice & clean, it takes 5-6 drops to prime it. I found that what worked best with that atty was to prime it, then take ONE hit, and then add three drops and vape away. You will have to learn
the taste just before an atty goes dry just like the rest of us had too.
Personal opinion of course, but to much cleaning is a mistake, atties work a lot better with a little bit of crud buildup in them.
I blow mine out from time to time, but I think I last "cleaned" my atties last December, or maybe it was in January. And, if I'm awake, I'm using a dripping atty.
