Both pathology and gas are hot and probably offer better income potential immediately after residency. I had no idea how much pathologists make while I was in medical school, and while I would miss the patient contact, it seems pretty cool--especially forensic pathology.
Gas is hot and gas-passers straight out of residency are routinely getting over 180K to join practices at the "associate" level. Gas is a very political specialty though and with the CRNA's and AA's and everyone else wanting to deliver anesthesia without actually attending medical school, the long term prospects for this field are still up in their air. Personally, I couldn't stand getting up that early...
