Default High rpm spinners

I am wondering what spinners are good for 25,000 + rpms. I don't like the idea of one coming loose at that speed. What is everyone else using?
Thanks in advance

Tru Turn spinners are the only ones I know of for the size range of engines I use.
Nelson FAI.40s come with a specially counterweighted spinner that effectively makes those engines externally balanced for 30,000+
I mention that just for trivia's sake, but it demonstrates that a perfectly balanced spinner might not be the best choice depending on application.

Thank you. I think they are capable of more than they are rated for.

the race engines have a counter balanced spinner to off set the missing material in the crank since the hole in the crank is so large. They still have a somewhat normal crank that has a counter balance for the piston and rod.
