I have seen a couple guys use them here and there and they are a pretty tall bridge, really would come in handy for one pocket. Anyone know where I can score one? 

A player from Missouri has a product called ez-jumper. It looks like a dog bone, like you describe. Ez-jumper.com is site for more info. I would say anyone who jumps with a dart stroke could use it to help their game.

Not the exact one I was looking for but it will certainly do the trick. Thanks. :wink:
