I've been experimenting again with the settings.  Most of my noise is in the glass.  The brain bucket for instance. If I set the reflection color to 25 it looks black. At 50 it looks very dark grey.  It's supposed to look like glass.  At Reflection 65, 65, 65 and transmission at 240 240 240, it looks like a very dark grey, not glass at all.  Am I supposed to set the reflection and tranmission like this for glass?  I  had them both up at 230 or so and it looked like glass but there was so much reflection and noise it was just a blob.  When you were explaining the settings, did that just apply to glossy items?
