guard - I strongly disagree. Gedolim are there to guide us - most of the time, they agree on areas of hashkafa, and if there is a majority, then there's no question. The torah obligates us to follow our rebbeim, and not to contradict them - one cannot disagree with a gadol byisroel, he cant say 'i dont hold like him', rather, i hold like someone else(assuming he's on the same madrega). I base a lot of what I hold of and believe of one one, maybe two rabbonim - rav avigdor miller zt'l, I look at as the gadol hador in hashkafa of his generation(along with rav shach, but rav shach didnt write in english, I only got to his sefer later on in my learning) - thats what klal yisroel has done for all the doros - when there were zugos, you followed them, since they were the leaders of the generation, after them came the nasi, the av beis din, etc.., down the line to the leaders of respective kehilos in europe and sfard, and even when there were leaders, there were the gedolei hador which the rabbis looked at as their leader(basically all the litvishe rabbonim followed the Gro, and the chassidim, the besht, and their respective talmidim, in volozhin and all the various chassidishe kehilos), so I dont understand what you're basing this idea of not relying on a rov. chazal say 'aseh lecha rov', just to name one source aside from the history of klal yisroel. The poskim discourage shopping around for rabbis - one should pick a rov and stick to him, this includes hashkafa.
