David, I just finished the red oak trim on an addition with lots of windows, doors and millwork. I really love the look of oak, and chose a Minwax brand "Natural" oil based stain. Watching the oils soak into the wood and bring the grains and patterns "to life" was thrilling. It colored the wood just enough to even out an minor flaws. I then used three coats of hand rubbed Minwax poly as a finish. The 3-M flexible foam sanding blocks were a blessing. When I needed to match the natural pine on the interiors of the Pella windows, a 50-50 mixture of "Natural" and Golden-Oak" stains on the pine did the trick. As for the stain and poly all in one, I was really afraid of the lack of control over blending and rubbing the wood, with all of that expensive millwork. But I guess if you try a sample and like it, you have saved some time. Hope this helps, these are just the thoughts of an amateur wood lover.
