DOUBLE FISH 820A ATTACK
This product is suitable for close to the table hitters and power blockers who also need spin. 820A has a conic shaped pip base that boosts power and spin, the tops are rough for extra grip.
I gave 5 stars based on comparison with other short pips out. I use this on my backhand and it does everything I want. It produces surprising spin on backhand serves for a pip and plenty for topspin counters. 802 40 is also good but this is better.
