I had planned on using 5/8 sheetrock on my ceiling covered with either reed cane or bamboo fencing for a finish something like this-

I am now thinking I might prefer the look of rough sawn lumber instead. My question is- Would the extra weight on the ceiling be a structural concern? Rock is already up d* and I figure I may add another 1500 pounds or so adding the rough sawn (complete guess).
Here is a shot of my roof framing, collar ties up high have since been installed.

You might check with Georgia Pacific or Louisiana Pacific and see if either one still does a product one of them marketed several years ago It was a T&G little less that a quarter inch thick and about four inches wide bundled in random lengths. Might be just what the doctor ordered. I did an office in it and turned out very nice. One side was planed with a Ved edge the other side was rough cut.
Thanks Rick, I was wondering if something like that might be made. I'll check into it.
I guess it might have been helpful to include some of the roof specs in my original post so here they are-
12/12 pitch, ridge board, 2 by 10 rafters span apx. 14 ft., 2 ft. OC, rafter ties every 4 ft., collar ties every rafter.
Both Big Blue and Orange Boxes carry it where I am. Not in the loose boards area but in the millwork area. Comes packaged in random lengths like Rick said. 5/16" thick IIRC. Big Blue here carries it in a couple of different patterns.
Type X weighs 20 pounds more than 1/2" per sheet, and it is code in some locations now. An old-fashioned plaster ceiling weighs twice as much as 1/2" drywall. Just something to consider.
