Good posts. 

Being past your state/fed SOL only relives your from the threat of an enforceable lawsuit for collection.

If you borrowed $1000 from me, and did not repay it, expiration of the legal SOL would not quench my distaste.

Creditors are usually corporations, so it is a bit easier in the mind of some to stiff them.

But a debt owed is a debt owed.  Having it remain in your CR is only right, even if they can no longer legally collect.
