You are going to get a bunch of different opinions clear across the board, I would reccomend to do a search first then see if you still have any questions. IP winny is discussed atleast 2 time a week it seems. Do a search and you will find TONS of shit about IP winny. I have some IP winny (oral) and hoping to god its good... *crossing fingers*... I will let you know how it turns out.
But Like i said, there are tons of diff opinions on IP's winny... do a search real quick to check it out.
