This is just my perspective, but if I had another 70+ k to drop on PCFG, I would do it.
I know many would say that such an action would be sheer madness. But what the hey, you only live once (I guess that would be up for debate if you believe in reincarnation, LOL) and so far pcfg has given me one heck of a reward for the belief that I have put into them. And, there are many (including me, obviously) that do not believe that the uptrend is anywhere near a halting point.
Yes, the thought that not too long ago the PPS was less than half of what it currently is does make new buys painfull. But, the point is to focus on the long term potential!
As I said, (in one form or another) make the choice that you are comfortable with.
