The Mantra H is a 9.4-speed hard (47.5°) Japanese forehand tensor, discontinued.

The Yasaka Rakza X is a 47.5° grippy tensor (8.4 rating) with linear, predictable response, high safe throw, strong short game and forgiving touch—works both wings and priced around 50 USD with good value.

Both are hard-sponge advanced rubbers, but Rakza X is still available, versatile on both wings, more affordable, and easier to control thanks to linear response. Mantra H is slightly faster and discontinued. Rakza X is the practical modern choice.
