After years of paying the standard repayment plan for student loans, I moved to income based deferment on my student loan, and I like it because it actually goes by what my income is, not the loan amount divided by months, and I can still make extra payments when I can. The reporting changed to reflect it, but I really don't think it changed my scores (I paid off my cc's, so my scores actually went up, but I don't think the sl had anything to do with it). You're not really paying less than a full payment, even if the amount is less than it would be on a standard plan, because, your full payment is whatever they calculate based on your income. So, as long as you pay the amount they say under the income based repayment, you're paying the full amount, it's not reflecting as less. If that makes sense...
