The cloud gray ones are nice, and the colours on the orangutan ones are quite bold, admittedly. I've seen guys riding the chubbies on sand bike tracks and keeping reasonable amounts of speed. They seem like really good wheels overall for a cruiser board, while not being defeated by a mere pebble. If you choose to get new trucks, Bear trucks are also a good choice, with a really nice leaning turn, but that's just my opinion. They are made by the same company but indy hollows are a really good choice.
