Justin Rose's New Putting Grip?

[Harp stein]

I noticed it on Sunday at the Wells Fargo (I think that's what was last weekend), he's doing a claw grip but not like most other claw grips I see. I've been trying to do something similar, the "classic" claw grip is too much for me I can't seem to get over having my whole right hand essentially inverted which forces the right elbow to stock out like a chicken wing. Just doesn't feel right or comfortable.

Anyway, I've Googled for pics but all I can find is a couple stories saying he adopted it the week before The Masters. Anyone know of pics or more info, it looks like he has one finger on the edge of the grip and the rest of the right hand "behind" the grip between the grip and his waist? I've been trying a few things and was just curious, was hoping to see pictures.
