"" I would rather have a phenomenal ox tail stew ""
I completely agree with you ...
the tastiest meat comes generally from the Meat that Works.
tails work a lot. they are now Chee-Chee ( only God knows how to spell this )
and therefor $$
and none of them come from an Ox.
they come from a 1 1/2 YO Steer or so.
however , they still have had to work. so does the ' cheek ' but that's pretty CC now two.
Id try to find some Neck muscles . best of luck.
I do think it might be worth trying a flavorful but less pricy cut of meat
ie Chuck ? and age it a bit in the refrig.
and pretend its an Ox's tail.
since you can't find and Ox , that's only a 1/2 fib.
just saying.
