It takes some skill to bed 2 piece mounts on a rifle so that they are co planar and parallel with the bore within 2 moa or 20 moa lower, if that is desired.
It takes much less skill and fixturing to mount a one piece to that quality, so that a scope with the reticule centered in the tube starts out on the paper.
But the one piece kinda gets in the way of the fingers in loading the magazine.
EGW makes great one piece mounts for reasonable money.
The word 'forum" does not mean "not criticizing books."
"Ad hominem fallacy" is not the same as point by point criticism of books. If you bought the book, and believe it all, it may FEEL like an ad hominem attack, but you might strive to accept other points of view may exist.
Are we a nation of competing ideas, or a nation of forced conformity of thought?
