Through discussion on forum, I am led to believe that QT should should endeavor to use unspent outputs large enough to keep transaction below threshold that would incur additional transaction fee. This does not seem to be working for me. Please see

for evidence of large unspent, able to cover entire transaciton, and

for how the transaction was made up of seven small unspents instead.

Bitcoin-QT v0.8.6-beta on OS X 10.7.5

Litecoin with coincontrol shows lots of useful details for unspents. One missing feature that would help in this case would be if coincontrol were to show what unspents would be selected in automatic mode. (coincontrol isn't in a release version of bitcoin yet, only litecoin and special bitcoin builds)

Duplicate of "coin selection code does very badly in some cases #1643"
