Narrative:
During the takeoff roll at approximately 130 KIAS; which was below the V1 of 136 KIAS; the captain's eadi failed. I rejected the takeoff and returned to the gate. The speed of the reject was above the company SOP for a rejected takeoff for this kind of malfunction. It was a split second decision I made for a few reasons.1. It was nighttime with low overcast and occasional snow. 2. Mountainous terrain 3. Empty aircraft; light weight. 4. Extremely long runway. After the reject I had to taxi up the runway to reach the next taxiway and still had half the runway length remaining.5. I did not glance over at the first officer's eadi to see if it was still operating. I feel my actions were safe for the conditions at the time. I felt that flying in an area of high terrain at night IMC with a primary flight instrument failed would be more hazardous than rejecting the takeoff on an extremely long runway with no passengers on board.

Title: B757 Captain reports rejecting the takeoff on a ferry flight when his EADI fails at 130 knots; which is above the speed at which his company suggests rejecting for this anomaly.
