Both are top attacking tensors, but they throw differently. Tenergy 80 is fast and direct with a lower throw and elite, forgiving blocking. The Fastarc G-1 has a high, safe arc that makes opening loops consistent and carries heavy spin, with Tenergy-like durability, at a lower cost than Butterfly.

Pick the Tenergy 80 for a direct, low-throw attacking feel and the best blocking. Pick the G-1 for a higher, safer looping arc and better value.
