I find it amusing how his size is brought up as a disadvantage like he is disabled, he is a professional athlete. If your body is not right, do something about it, go to the gym, put some extra weight in your suit. He has heaps of options to deal with his weight issue ..... McDonalds, KFC, Burger King. The bigger guys in the series like Redding and Rossi (who is looking like Skelator BTW) have a tougher challenge to overcome their weight issue than just having to eat more junk food. Could think of worse problems to have.
I think if Danni could develop and grow a nice 10kg - 15kg pot belly it would sort his weight issue out no sweat. The Stomach is a good area to put weight on, its nice and low when he hangs off around corners. Alpine star could make a special little suit to encapsulate his belly.
