I know absolutely nothing about Dura Ace pedals but I finally got Speedplays and those are GREAT to ride... I had heard many people say that you have to get used to them and you really need to practice on the trainer... had me all freaked out the first time I rode them... so I get on my bike and click... I'm off with no problems... they were SOOOO much easier than my other clipless pedals! If you haven't considered them, they might at least be worth looking at...
There is a fine line between "hobby" and "mental illness".
