Linux has a filesystem specifically made for CF "leveling".  Which will
attempt to keep the number of read/write cycles even across all the
cells in the CF card.  It's called JFFS.  Then you do some calculations
on how long it will last and plan for maintenance... maybe even run from
a RAM disk with regular sync to the CF card at reasonable intervals for
your data.
