Question, but since it isn't listed I assume you havn't looked at / changed regular Helium at all? I ask because from what I've seen with the mining rates and the in system sellpoint of roughly 950 per unit, I think it may actually be one of the highest profit per second routes in the game. This is especially true considering the small system it's located in and the nearly absolute safey (from the field a stationary battleship is only 10k away).
