Who is running a non-steel stator in their convertor with a trans-brake? How is it holding up?

I have two convertors:
1) Turbo Action 10" 3800 Stall
2) Dynamic 9.5" 4500 Stall

I bought a trans-brake last year, but have not installed it yet. Too worried about damaging the convertor and tearing up parts, so I have just kept foot braking it. I know the convertor companies recommend a steel stator in a trans-brake application, but would like to hear some real world experience on this.
