I think they are also inherently are more background radiation 
tolerant.  But why they have whatever tolerance they have is not really 
the question.  The question is, just how hard are they?

If they have parts that are 100 krad tolerant, then there is a good 
chance all their parts are (probably come off the same wafer).  They 
just have more paperwork with them, hence the extra cost.  Assuming the 
cost delta is significant, I'd try the less expensive version and test it.

Lyle, I assume Heather is driving!!!
