Actually, I've thinking about the increased value of the second 17' log in
relation to the annual increase in the value of the tree. I'm on a small
enough scale that I can measure dbh annually and harvest individual trees
when their annual increase in value drops below what a replacement would
yield. If pruning the second log can push back the "retirement" date
substantially, then the extra work required to prune the top log would be
offset to some extent by the reduction in frequency of harvest.
Of course, I've also thought of pruning them after they have been felled,
but there aren't many southern foresters in the log buying business up here
