cupping worse for 1X6 than 5/4X6???
I see a lot of posts about cupping. I'm thinking of putting down a new ipe or massaranduba deck of 6" boards. Yes, 5/4 is more $$$$ than 1" but I'm willing to pay the extra $600 if that gives more chance of a good deck. Maybe 4" width would be even better but what about the 6" width lumber?
