That is an interesting point. Some of the guest posers wear shorts and it doesn make a huge difference. But they would need to be smaller shorts.
As for the Men's Physique division, the biggest complaint I hear from the women is that their shorts are too long, and you cant judge their legs at all.
Question - why do you keep calling them 'thongs'? Have you actually seen what a thong looks like on a women, or do you wish the men would wear these thongs? Come one now, these type of suits remind me of the European suits they wear at the beach. Whereas they won't wear it in the US, or perhap the times are a changing in terms of conservative values, they still are not thongs.
