@obsolete, have you tried IND/PHI? I would be interested to hear thoughts on its OPness or otherwise from the master of IND.
I just tried an IND/PHI immortal game (got stone early) and am starting to have doubts about it. I ended up with an almost OCC type capital, plenty of land, and a ridiculous (for me) tech rate. Although the map was pretty ideal, it might be that IND/PHI is too straightforward in such circumstances.
