Then you want it visible for freaking and accessible for screws.
I’d take a good look at the hollow spot between metacarpals on the back of your hand, just behind (but close to) the knuckles. There’s kind of a divet in the meat there. It’s where I tucked my Titan (s). One got installed a little far back (my fault) and is more visible, but the one that’s down in the groove is damn near invisible unless I don’t want it to be.
Hang on a sec, I’ve got pics somewhere.
