do u track canroys' hedge programs? can u tell

us the difference among canroys, I wants to buy some for a long time, but do not know which one is better, heard from fool.com discussion board, a guy prefer pvx. I currently hold ent, was waiting for it to start distribution, hence a big spike in share price, still waiting now. A good thing about ent, is that its financial crisis came earlier than economy crisis, hope it is well prepared now.
