OK
I looked and was wrong - It's a DK Upright at 86mm or so.
I found that some of the measurements vary. I guess its based on the years of use. I measured a couple of my balls (Yeah that's right) and found that the sizes do match what the Web site says.
86mm DK Upright
82mm DK Cocktail
80.5 The rest
Either way -- Free Bump
