I know that this will not make any difference for the index itself.
As you said, this may be slower to create the index (millisecond? seconds?).
But, the string used in the seek will be easier to construct and can be used directly as a treeview key (and this is the case here I think).
I think the previous paragraph is enough to justify the use of the padded string IMHO.
