ebb's need a bigger shell so not viable if your frame is aluminium. i would go for the white industries hub getting track ends welded in is going to be difficult as you need to heat treat the frame afterwards to retrain strength (welding steel is cheaper/easier and more readily available).
one thing to watch is bb height and crank length. low bb and long cranks means possibility of pedal strikes
