Decided to research your question and came up with an interesting page here:
https://ttgearlab.com/2020/01/01/xiom-novus-series/
Looks like TT Gear Lab was hired by Xiom to design a bunch of blades in the "Novus" line. According to the page, at least 16 blades were designed by them. They feature the 'old handle' style which was designed by them and were separated into different groups.
Xiom Solo was in the "Tourwood" series, and the initial specs of 1.76 primary elasticity and 1.67 central elasticity means it's about as fast as a Samsonov Force Pro Black, but with slightly less dwell. For comparison to other popular models, this falls in between the speed of a DHS Long 5/Butterfly Innerforce Layer ALC (1.62-1.64 elasticity) and an Innerforce Layer ZLC (1.9).
I'm not sure if those specs have changed or not because I expected from reviews for it to be slower and softer than something like a Force Pro Black.
More interesting to me is that the Xiom Offensive S (or at least the version that TT Gear Lab designed) is listed as having less dwell and more kick than both the Xiom Solo and the Samsonov Force Pro Black. At a Ec/Ep ratio of 0.94, it has less dwell than a Clipper, a DHS Long 5x, and even a Stiga Carbonado 190.
Either the readings are off somehow on that particular Offensive S, or something is very off with TT Gear Lab's general methodology. How does a 5 ply like the Offensive S with it's composition have less dwell/hold than an outer carbon like Carbonado?
Anyway here are links that I used to make these comparisons:
