Wow, I'm really surprised this hasn't been snapped up as it took me ages to track them down and I had to buy a job lot just to get one for myself.
You lot must find no issues with the shape of the Go, as for me this finally allowed me to get those higher Golds on Wipeout and all the AAAs on Outrun as it makes it so much nicer/responsive to use when your hands are in the "right" place.
