Is anyone familiar with the reliability and curve of the "constant curve" Sunshine Infinity RDM 370?

I have used and tested quite a few of them (100% models) in various sizes including 370. I believe they were made by Triana in Italy.

They have been excellent. Slightly smaller diameter than some other Triana made masts for other brands which means probably slightly stronger. Curve and stiffness has tested well within specs on all those I have tested (4 or 5?), (Same story with the Sunshine Infinity SDM's I have tested).

The weight of the 100% RDM's is excellent.

Here is one test result from that mast compared with 100% RDM KA Mast:

Exact same bend curve and ever so slightly softer bend stiffness. The difference is not enough to notice. Different masts from the same brand and batch often show up to 1-2% curve and 0.5 Stiffness Index, and you can sometimes get this much variation just by rotating the mast 180 degrees and testing again.
