It's actually not smart to use anything over m165 at the moment. Some times we've had weird needs for modified functionality. As the programmers with the specific needs, everything is cool because we can work around any bugs we have. There is nothing catastrophic but little quirks show up.

All in all though, these custom build don't do much more than the m165 you are using. I still put m165 on anything I rent outside of my own use.
