Both top-tier Nittaku tensors deliver excellence through divergent paths. Fastarc G-1 offers heavy spin and real speed together, a high safe throw angle making opening loops forgiving and consistent, and Tenergy-class durability at lower cost. Proven and hugely popular for all-court attacking on either wing. Firm 47.5-degree sponge rewards technically sound strokes but suits intermediate-to-advanced players.

Hammond Z2 is a harder Japanese tensor (52 degrees) demanding active, well-timed strokes. Exceptional looping and counterlooping power, above-average durability versus typical ESN tensors, medium arc and manageable throw angle. Made in Japan for distinctive non-ESN character. Active blocks and smashes are extremely dangerous. Trade-off: very unforgiving of passive contact.

G-1 targets intermediate-to-advanced attackers wanting heavy spin, real speed, and forgiving arc on either wing. Z2 targets upper-intermediate and advanced loopers and counterlooping specialists who use active strokes and need consistent performance with a harder feel.

FAQ

Which has a higher throw angle?

G-1 has a high, safe throw angle. Z2 has medium arc, more aggressive and lower.

Which is more durable?

Both offer excellent durability. G-1 matches Tenergy-class performance over months; Z2 is above-average versus ESN tensors.

Which is more forgiving?

G-1 is more forgiving with its high arc and safe trajectory. Z2 is very unforgiving of passive or mis-timed contact.

Which is faster?

Z2 (52 degrees, speed 9.0) is harder and faster than G-1 (47.5 degrees, speed 15.0 Nittaku scale). They measure differently.

Which suits both forehand and backhand?

G-1 is proven for all-court attacking on either wing. Z2 is optimized for forehand; backhand use is secondary.
