The Xiom Zeta Offensive all wood blade is koto 7 ply blade from Xiom. The ZOC is about 87 grams in weight and about 6.2mm thick. It feels harder than the Xiom Solo which has an identical composition. The Xiom Solo despite being a 7 ply blade, the feel and flex is a that of a 5 ply blade and the speed is only at OFF- and not a true OFF blade. The ZOC feels a tad harder than a Clipper CR with more speed and power. The blade is an attacking blade but offers very good control slightly lower than that of the Solo. The blade feels like having a semi-hard feel with some flex. When paired with a a powerful rubber like Omega 7 Pro, it is excellent away from the table while maintaining control. This is also a cheap blade priced at about 50USD.
Zeta offensive is a superb 7-ply all-wood blade. It can generate decent spin, and has lovely control in blocks and drives. I have paired many rubbers with it and they all have worked well. El-S, Mantra, Gewo FT48 all suited well to the blade. The throw is medium-high and provides ample safety over the net. Despite that, you can still execute flicks and short pushes well. At 40 euros, I don't think there is a better all-wood blade in the market and it can help immensely if one wants to progress to a faster blade from a standard 5-ply one.
