my notes for TARGET PRO BLUE 38,5° : Blue sponge, this is a hard traditional chinese sponge made for fit players with strong technical ability.
Tackiness is very high. Needs a bit of break-in before rubber sheet performance stabilises but remains very grippy. It produces lower arc and the throw is sensibly lower than Tenergy 05 or Dignics 09c.
Power is unleashed when played fast with fully developped movements. Small game: after break-in, very predicatble and precise.
Recommended for high level players. Much less reactive compared to tensors.
