After nearly being defeated by my last 36" round I decide to play it smart and balloon pump this one. But man That didn't make it any easier as now my arms got a big workout. A min of pumping to fully get it to where I want it, I tie it off and start playing with it. Bouncing it, rolling on it, bouncing on it, and of coarse putting my whole weight on it!. In the end I decide to give it an honorable with my katana. I truly had fun just playing around with this one.
