Thinking of a lazy MF build

Given that I've already played straight spectre summoner twice, that one's out.

For the new leagues after Ambush/Invasion, I want to make a MF farmer in the HC league. For once I'll actually have the time to put into playing, so a farm character and then some interesting other characters without being severely limited by finances.

After discussion with my theorycraft buddy, we settled on RF because why not. It's easy to level as SB, in theory. And doesn't really get lazier than RF. Maybe I'll do a CWS/CDT build in SC but I'm not sure it's entirely appropriate for HC.

RF - AoE/conc.e - IBD - IIR

Or something. I can usually afford a 1ex major item by level 60~ on a new character, so Phoenix is just about right.
