Dear chaverim,
I believe it is you that has it backwards. He is not Rabbi-shopping for a specific psak, which would be wrong. He is looking for a Rav whose hashkafa, and view of Yiddishkeit is one that he would be able to identify with and take comfort from and grow with. Would you stay with a physician who only believes in surgery if you believe in homeopathic treatment or would you go shopping for a doctor who supports your approach?
