I'm looking to have a dedicated plane (or iron) for flattening boards. Given that I already own a LN no 62, would I be better off with a toothed iron for that or picking up a good Stanley no 6? Where I'm located, oak is readily available from local sawmills and walnut (though more expensive) so I mostly work with those two species.

Realistically speaking, I'm considering using this plane to flatten one reference face of boards - which I will sometimes run through a thickness planar for final thicknessing.
