From memory, the last ball on that clip was the original solaris... but if its the one that gets back a lot, it was at the end of the night! haha

Yes the orange ball is one we have been testing.. the videos shows the roll of the balls well, but they are tested on a few different conditions so to be honest its hard to make a direct comparison between the balls. For example, the reaction from the Epicenter will be about as strong as the yellow ball you seee tearing off the gutter!
the video quality on that video isnt great (was compressed alot for the expo display screen) so I will upload some bettershorter clips soon.
Cheers
