Grob and Reverse Grob

I started playing the Grob, and the Reverse Grob on chess.com to see what would happen!  I was shocked after a few nice positions coming from it, and a few wins of Black's a8 rook!    I looked it up on Fritz' database.  Of course, the normal Grob had been played a few hundred times at GM and IM level.  And the Reverse Grob (1...g5!?) had also been played.  Five wins!  (21 losses and 7 losses, too!)

Has anyone else had any experience playing with either colour with these two openings?
