My opinion is silver is still heavily manipulated down in price and right now you should be stacking. Look at your other investments. Is 15% too much to put into silver? Only you can answer that as a percentage of your entire portfolio. 10%?

Me, although I haven't bought any in a while, I would look for when the price goes down and then buy some. Even if it is only a few ounces.

I don't look at silver as an investment though. To me silver is a hedge against the future and what these maniacs are going to do to the world. So I buy and hold. Never sell!
