Using this in 2.1mm Red. After less than an hour, the tackiness goes away. Once that happens, the rubber becomes a good close to the table control rubber with good blocking, serves, pushes, and drives. The sponge/rubber combination lacks the power/spin needed to do loops consistently for me. I do like the light weight though and recommend this for players under 1500 (like myself) who don't want to emphasize loops.
