If you do end up using the 3/4 t&g cut your longer boards into smaller lengths 3-6 ft (especially if by yourself).Take a router with similiar shape as the edge of the t&g and router the butt ends of the boards,this really looks nice.You don't even need to fall on a truss,let them run random.The T&G will give plenty of support.May sound like more work but it isn't it goes really fast.
