What is important is the thickness of the ring because this will determine the length of your keystroke.
There is also hardness because many of the generic ones made for various industrial purposes tend to be quite hard.
I would start with the thinnest and softest ones that you can find.

“No political truth is of greater intrinsic value, or is stamped with the authority of more enlightened patrons of liberty: The accumulation of all powers, legislative, executive, and judiciary, in the same hands .… may justly be pronounced the very definition of tyranny.” —James Madison, Federalist 47
“All the powers of government, legislative, executive, and judiciary, result to the legislative body. The concentrating of these in the same hands, is precisely the definition of despotic government. An ELECTIVE DESPOTISM was not the government we fought for; but one .... in which the powers of government should be so divided and balanced among several bodies of magistracy, as that no one could transcend their legal limits, without being effectually checked and restrained by the others.” — Thomas Jefferson, commentary on Federalist 48
