I was sceptical at first, this being marker of course, but everything I have heard about the Duke is that it is as good or better than the hype. Which is staggering. Some people say they will never need another binding, for alpine or touring. I plan on picking up at pair at the end of next season, first off seeing how durability plays out and to save on price.
From what I understand, the Jester is a slightly lighty version (no plate underneath with the walk-mode) but otherwise identical, leading me to believe this will be a solid 16 DIN binding. It and the STH 16 will probably be fairly close competition.
