Thanks to all for the replies. The house is painted, so stain and
matching are not a problem. If we go with the pine I will be sure the
backs and ends of the boards are well primed. I know nothing about
Hardiplank - I will do some research. John, did you use the Hardiplank
on your whole house? We will also be doing a major kitchen/bath
addition in the next year or so and you have given me food for thought
on replacing the entire shell.
