Flavour N'abania VS Iyanya. Whose Waist Do You Prefer? (LOOK)

Flavour and Iyanya are two hot and sexy dudes that seem so obsessed about their waists. In their numerous music videos, they pay more attention to dance steps that has to do with waist winding. The flexibility of their waists sometimes appear incredible to me as they twist it 360degrees. 

In Flavour'smusic video "Shake", the aerobics he performed with his waist are eye popping. Also in Iyanya's music video, "Your Waist", his waist was like an elastic rubber band. As many of you that have seen these music videos, compare their waist-rolling abilities and tell me whose waist you think is more flexible.
