The Proideal Mallican II isn't a fast or slow rubber; I'd rate its speed as medium. These pips aren't super soft—they're a bit stiff—so they bend and create a decent but not overly dramatic disruption.
This isn't a rubber for playing and chopping far away from the table. I'd venture to say it's best for playing close to the table, maybe mid-distance at most. It has a low throw angle and is very insensitive to incoming spin. The chop stays stable and low, and you can even hit the ball a little with it.
In my view, though, it's perfect to pair with slower Blades because its speed can get away from you a bit.
The rubber has some pretty interesting properties, and in its normal versions, I'd say it's an average rubber. The one everyone knows and loved at the South American championships is the cured version that some players use. The cured version is horribly toxic and dangerous, but that rubber isn't legal for championships or ITTF play if used in that state.
Therefore, the normal versions aren't nearly as damaging as the cured version, which has like 10 or 15 different curing types. That one is the most dangerous and the most expensive due to the treatments they apply, costing $30 to $199 USD
