Yeah or even more so. I just realised you may not even want to fight spinners so it doesn't matter. But if you look here on Beta can you see how it's just one smooth continuous angles and shapes? And how anything nasty trying to get at it would sort of deflect rather than chew? If it helps I can sketch something to show you with regards to your robot when I get home.
