Hey Randy:

I would be concerned that boo that is completely brown and has been cut for several months may not be as durable and long-lasting as freshly cut boo but I've not tried it to find out. We have so much boo available around here that there's no need to use any that may be less desirable.

I do know that boo that has been in the water for a while and then gets exposed to the air when the lake level goes down seems to break down and get brittle.

We have bamboo condos that have been in the water over four years now and the only ones that I've broken any limbs off of and brought pieces up on a hook from are ones that the tops were above water at some point.
