Nice thread =D
I'd add 1" and a half or 2 to lenght, so i get till 9" and a half or so, and def. would add 1" to girth, making it 7. I'd make it a little bit thicker in the middle and increase the head to a knob size, keeping it's shape. I think I'd curve it up instead of down, make the head a little bit less sensitive, double size the balls and make them hang way lower, and make the whole thing a bit darker.
I'm happy with it now, but if I could.... lol!
