You could always situate yourself in a Byzantine Catholic Church before you make the jump.
I figure that personally, since I am Protestant, it doesn't matter if I choose Orthodoxy or Catholicism seeing as I am neither, and in both cases outside of the Church.
However, I don't think I'll choose Catholicism. The Filioque is the real issue. Was it part of the Apostolic Deposit from the beginning or not? I am not convinced that it is.
You have to convince yourself on what Church is 'the Catholic Church'.
"In the Catholic Church itself, all possible care must be taken, that we hold that faith which has been believed everywhere, always, by all. For that is truly and in the strictest sense “Catholic,” which, as the name itself and the reason of the thing declare, comprehends all universally. This rule we shall observe if we follow universality, antiquity, consent. We shall follow universality if we confess that one faith to be true, which the whole Church throughout the world confesses; antiquity, if we in no wise depart from those interpretations which it is manifest were notoriously held by our holy ancestors and fathers... he is the true and genuine Catholic who loves the truth of God, who loves the Church, who loves the Body of Christ, who esteems divine religion and the Catholic Faith above every thing, above the authority, above the regard, above the genius, above the eloquence, above the philosophy, of every man whatsoever; who sets light by all of these, and continuing steadfast and established in the faith, resolves that he will believe that, and that only, which he is sure the Catholic Church has held universally and from ancient time; but that whatsoever new and unheard-of doctrine he shall find to have been furtively introduced by some one or another, besides that of all, or contrary to that of all the saints, this, he will under, stand, does not pertain to religion... it is incumbent on all Catholics who are anxious to approve themselves genuine sons of Mother Church, to adhere henceforward to the holy faith of the holy Fathers, to be wedded to it, to die in it." (St. Vincent of Lerins)
