Butterfly Dignics 09C blends Chinese tacky characteristics with European tensor speed, outstanding for looping and counterlooping with extremely grippy topsheet and heavy spin. Extremely effective on serves and short pushes, delivering safe high arc and strong over-table control with excellent durability. Heavy weight and high throw angle require stroke adjustment and demand high swing speed to reach potential.

Donic Bluestorm Pro AM is a versatile, lighter tensor (around 50g uncut) balancing speed, spin, and control with multi-gear feel—output scales well with player technique and power. Excellent across loops, blocks, counters, and short game with good durability, but mid-distance power drops under very high-paced conditions. Both target advanced players, but Dignics 09C specializes in tacky-hybrid spin production while Bluestorm Pro AM prioritizes versatility and accessibility. Choose Dignics 09C if extreme spin and heavy topsheet suit your power; choose Bluestorm Pro AM if you want balanced all-around performance and lighter weight.
