Rav shopping? Nothing wrong with it as long as you follow the psak after the shaila has been asked of the Rav.
I once called a famous Rav in Washington Heights with a shaila because I heard that he was maikle in a certain thing. To my surprise, he was not but I had to follow his psak since I asked him the question. Also, I once asked my Rav a shaila on the very sensitive and delicate matter and he told me that he was machmir in this inyan and that I should ask Rav____ because he had a different opinion which was l’kula.
What about chumra shopping; anything wrong with that, because that what a lot of you in the CR do?
