so it's better for one to be paying a ton of interest to bank to keep FICO score up than to pay it off if one has the cash immediately?
Not necesarily, that's a totally seperate question and won't affect your score too much.
Additionally, it would be idiotic to consider your FICO score when making that decision.
FICO scores are mainly important for people who will be needing to buy a house or a car in the coming years. From what I understand you aren't in that category.
