I bought my first ball, the Amp, in January after a demo. It was suggested to me to buy a dull ball with a lot of surface. I looked at a wall full of balls and picked out the Amp because as a kid I'd always wanted that Blue Hammer. Anyhow, I'm fairly happy with my ball but my mind can't help but contemplate what Hammer I might want next. So, do you own an Amp and other Hammer balls. How do they compare, what's your favorite, when do you use which ball?
The Amp doesn't seem that popular a ball. Any ideas why?
Oh, I'm likely to only have one ball so anything I use will need to be versatile.
