Default NE1 have new coordinates for non-singular event horizon?

What coordinate system would describe be useful for a
metric around a black hole that would *not* blow up at
r=R_S?
thanks

Why would anyone like to plot a fictional infinity in a single point
of space, using a metric realworld coordinate system?

Some candidates...
Eddington-Finkelstein
Kruskal-Szekeres

Probably more.

Why would anyone [you] comment about a subject of which they [also
you] clearly have no education in?
