Ryosuke Irie...can he do it without the suit?

Today in an article, Japan's Ryosuke Irie talked about his mission to break a World Record in an approved suit this weekend at the Japan Open. (It was at this meet last year, you might remember, that Kosuke Kitajima broke the 200 Breast World Record and Irie himself first went under the 1:55 barrier in the 200 Back.) The question: can he do it? And if so, the 200, the 100, or both? We shall soon find out.
