Has any Body Used These

Sorry to say I haven't. The stock Revo shafts are quite solid and hold up well to BL power. Plus, the stockers are light. Something to consider: Those have a t-bone on one end, and if using RPM arms, the flex in the arms may cause the dogbone to pop out of the cup. I'm not even sure if this would be a problem with these TBH, just something to think about. They do look nice though.
