The Nexy Spartacus is a controlled carbon blade with Hinoke outer veneers. Kinda thin at 5.7 mm has flex and a softer feel. Dual impact gives a lower low gear and a faster top gear. Overall, this is not a bouncy OFF monster. Controlled offense is the name, but with a top end in OFF range when you do a full bang impact.
Here is a review thread on a TT forum.
