Without the RXR being built and not installed, it would be hard to compare "whippiness" to the Trono.
I can tell you that the Trono would be the stouter of the two. And more expensive.
If you're looking for a more flexible shaft, I'd consider either the RXR.
If weight is more important, go with the RXR 45gm.
The Trono is 55gm as is one of the RXR.
