Hi McCartney,
I'm betting on lee side. I've seen quite a few oriented stones with radial flow lines on both sides with the lee side showing, in all the cases I've seen, the fainter lines.
Here's a quick few photos of the first one I could put my hands on, a little Chergach I got from Geoff Notkin:
lee side:

windward side:

With my quick and dirty photos the lines look a lot fainter than they really are(compare Geoff's photo of the front to my more humble effort).
Cheers,
Jim Baxter

This is an Allende. I'm not sure I understand the orientation signs I see.
I see a star flow line pattern which indicates this side is windward. But the lipping on the NW side hints the side is leeward. So I'm a bit confused.
Any ideas on alternate interpretations?
