At the moment the answer is simple. GERS is still a bottomless pit. Maybe when it's more sure to make money on it, I will might invest in both.
By I'm investing to make money. I'm finding the chance to make money at PEIX more likely then the chance with investing in GERS. Sure, GERS has the potential to give huge return once there is no need for lawsuits any more. But so far, I only did see it move down. But to still have a chance on a huge return, I buy lottery tickets instead of GERS, they are cheaper when you look at it in terms of loss so far.
