If you need to get solid panels finished at .75", do you prefer to start with rough wood of 4/4 or 5/4? I realize that some woods are less likely to move compared to others. I use primarily walnut and cherry and I find that 4/4 that has been jointed and planed will sometimes drop to below .75" to get it flat. With 5/4, there seems to be a bit more leeway although the cost is higher. Would like to hear different opinions. Thanks, Glenn
