But to go and become "Breslov" seems like a mistake to me.
That is from what I have observed. However for me personally I think, I have gained a great deal by the advice of Rav Nahman and also from my time being in Uman.
Still if my advice means anything to anyone, I highly recommend to stick with the straight path of the Gra and Rav Shach--at all cost.
[It is however to be noted that not everything within the context of the Litvak path is something I agree with. I am merely saying that there is a array of values in which there is an equal and opposite array of values that attacks it. So while the value of authentic Torah is the path of the Gra and Rav Shach,still on the opposing side there are pseudo Torah scholars that are demons that attack that area of value. However I am not saying that that is the only area of value. For example there is the area of music which is also a holy value, but it has arrayed against it music of the Dark Side. That is to say that every area of positive value has against it a value and forces of the dark side that attack it constantly.
This was cause of the Gra to sign the letter of excommunication. He had in mind to warn people about the forces of the Torah of the Dark Side that were attacking the Torah of Truth, authentic Torah.
[I believe that Rav Nahman would not have been under the excommunication based on the actual wording in that letter.\]
