Tradition should not supersede the Bible. If something in history caused the church to misapply Scripture, it is irrelevant how long practice might have been in place, it should be corrected, if it goes against what the Bible says.
Having said that, I think the principle of Sola Scriptura is often misapplied with many Protestants, because there can be a tendency to refuse to take context into account. I’ve had conversations with Christians, when you try to explain what was happening in the church during the period Scripture was written, they refuse to pay attention and just rely upon the literal writing without context.

The task is to determine what constitutes authentic tradition. How can we know which traditions are apostolic and which are merely human? The answer is the same as how we know which scriptures are apostolic and which are merely human—by listening to the magisterium or teaching authority of Christ’s Church. Without the Catholic Church’s teaching authority, we would not know with certainty which purported books of Scripture are authentic. If the Church revealed to us the canon of Scripture, it can also reveal to us the “canon of Tradition” by establishing which traditions have been passed down from the apostles. After all, Christ promised that the gates of hell would not prevail against the Church (Matt. 16:18) and the New Testament itself declares the Church to be “the pillar and foundation of the truth” (1 Tim. 3:15).
I agree and I don't believe that it does. Tradition does not supersede. It acts in concert, in harmony, with the Bible. The Deposit of the Faith which contains all of Divine Revelation is both Scripture and Tradition. It's a false dichotomy to separate the two according to the dictates of individual preference which is what sola scriptura does.
And there will be those who'll lob some verses, and I'll lob back, etc. ad nauseaum. The point is, that what was said, and what was done are just as important as what was written. Lex Orandi, Lex Credendi: How we pray is how we believe. That counts for something.
