So I recently acquired a high 14X Bishop..

I agree with butterfli, go to harps. I used to train there on 2x drop every 3 or 4 days, and I found 15 steelys. Awesome map considering you don't even have to move to hit the entire map. Even without 2x drop or getting drops at all; I atleast broke even. You're almost maxing out the monsters you can hit with Genesis. The mesos + etc is enough to break even.
