Allazar, the correct answer is "everything". There are some things that are not needed, but everything works. For example, low-resistance atty/cartos were only created to let a fix-voltage device run a little hotter, simulating higher voltage. With nearly any device, LR will run your battery down faster. With Darwin, just use SR and turn it up.
I have run the gamut on several atty/carto combinations, Boge 510d @ 3 ohm is what I like the best. I run it between 6.5 and 8.7 watts, depending on my day and mood.
