I treated myself with the innerforce zlf and have tried it out
it feels not too soft and with a very good, dwelly feeling. Immediately blocking felt very controlled and not fast at all (probably due to the slower wood outer plies). As I rotated more and used my forearm I was able to produce very fast and spinny topspins as the ball sinks into the zylon fibre more due to a longer and faster stroke. Touch play was very controlled unlike its timo boll series rivals which are very bouncy in the short game. The high toss of the blade came to an advantage to me as I didn't have to lift it over the net as much and could go for bigger shots.
