I'd like to hear the sides on Cast vs. HHS.

No point in spending money on any taps or dies that aren't HSS.

We're metric in the UK, for new work anyway, and maybe also a couple
of others like 26tpi brass thread and 40tpi model engineering. Anyway,
we use far fewer thread standards than in the USA. As I mostly tap in
no more than 3 threads, I can afford to have top-quality tap sets in
those sizes and just use a cheap set for backup.
