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.
