I like those aged Arizona Grips a lot. Many of the pictures on grips and designs included on grips make a gun look cheap, those do not.
To the OP. I have a stainless flattop 45/45 acp that came with their fake ivory. I did not like them at first but left them and they have no issues a decade later. Not sure who told you they might break, but I do not believe that. All polymers are sturdy these days. This is a picture off the net, but they do set the stainless off a bit.. Now I have grown to like them, and they are staying on the gun. I actually carry this gun on occasion. Nobody confuses it with an evil gun.
I have wood grips on all of my Ruger single actions and my other brands as well, except that one, which is a dress up gun. I also collect levers and try to match up my levers with a single action. Wood or something like that aged ivory by Arizona grips looks classy. Anything with a picture in it, does not, just looks cheap, burlwood and worm wood are for coffee tables, although they can look fine on a black 1911. Elk is fine, if American elk, stag is not, ain't no stags in America. Might as well buy a cheap copy from China.
But then I am opinionated about my single action guns. On my Redhawks and other 44s and 10 mms, and my collection of DA/SA wheel guns, I do not care, rubber with psychedelic colors is fine. I even have some with lasers in them, for different uses, of course.
But then, I once was a cowboy, raised cattle, entered rodeos, had a PRCA number and all that, and enjoyed the single action when on horseback. Guess nobody lives like that anymore. I do miss my horses, all have passed the last few years. A single action can go a very long time on horseback, like wire pliers on the belt, or a case knife in the pocket, even on a 4x4 and forgotten about, until you need it, and then it always works. I just see them as a classy historic tool, that too many people pay good money to make them look cheap.
What caliber is your gun? Mine with the fake ivory looks like the one above, the 45/45 acp dual cylinder model. Small frame but I love this one. I have others with the big frame for the Ruger only loads. The big one looks like this and has these grips.
Just one old guys opinion. Let us know what you choose And post pictures, single actions make good gun porn.
