Rav Asher Weiss in my personal opinion is an up and coming star who definitely will make it to the top tier of the gedolim hierarchy. And he deserves it. Listen to this shiur entitled "Ask the Posek" at the Young Israel of Century City. Fantastic! As R'Steve Brizel said in his audio roundup , "OK, I admit it, I’m a big fan. This shiur, in English, once again demonstrates you can have gadlus, humanity and a dry sense of humor."
