I have always thought of them as a sloggers bat to be honest, but I haven't heard many bad things from the people that use them, except that the life expectancy for these are generally low, but I have known a few people to have ones that have lasted for more than 3 seasons! I have never actually used one, (I will use most bats, but if I were to use a Malik, I would feel the obligation to slog, which I cannot do to save myself) but some of the biggest sixes I have seen hit are from folk using Maliks. Hope this helps!
Oh, and Asad hand picks his bats, so you are pretty much guaranteed a good bat if you go for a Malik from him.
