Tikkun Saufrim

Is there a tikkun which is available for writing a Tauroh according to our mesauroh?

Are any commercially available tikkunim correct (I practice lehning in a Tikkun Simanim, although I don't know how it lines up against our seforim)

I was about to post a similar question.

I've noticed that several Nusach "Rodelheim" siddurim (including the S'fAs Emes, Avodat Yisrael, but ironically not the Rodelheim Machzorim) have a chataph patach in place of a sheva-na in certain places. I have a Tanach that follows these rules, but it's over 100 years old. I'd also like a new, clearly printed Tanach (or Tikkun) that follows our mesorah.

The Koren Tana"ch (Koren Yerushalayim, 1962) follows R' Wolf Heidenheim, at least in Chumash.
