I got the spikey Royal Footbag. I think it's the weirdest spikey bag I've ever owned, and I try not to giggle whenever I kick it around (because it's so much fun to kick it around!). The spikes are pretty big, and it could interfere with dexes, but I think this would be a pretty cool bag for 4 Square!
I truly like the feel of the bag, and the aestheticism of Roy's work on the 32. But now that he's made another 32-color 32-paneled bag, I'm torn. Like, dropping-to-my-knees-and-screaming-to-the-heavens torn. These bags are just plain wonderful!
However, the long spikes on the spikey bag is fated to be a great crowd pleaser. I think I'll dedicate an entire session with this bag outdoors come mid-Spring.
