$400K in Student Loans: Federal vs. Bankruptcy Discharge?

Here is my plan:

Consolidate all 30 loans with Oklahoma Student Loan Authority (OSLA)...

...except one small $300 loan held with AidVantage.

Great Lakes was first pick. But Great Lakes (great company) is being absorbed into Nelnet (horrible company). I don't want my loans absorbed into Nelnet.

I'm leaving one loan out of consolidation as a safety in the event...

- OSLA mishandles my loans > I can consolidate the large and small loan with another servicer.

- I feel that paying off $300 on my own will boost my credit score (currently 706).

I may also NOT consolidate my 5% $3K Perkins loan. I can later consolidate that loan after 180 days to further drop the interest rate of the larger consolidated loan (6.9%).

Which leaves me with this question:

What is the benefit of paying off a student loan manually vs allowing the loan to be zeroed out through consolidation?

Is there any FICO benefit whatsoever?
