Nice interview. A couple of answers I found interesting/funny (not in exact words):
T11: how did you get into this business?
R.B: I was born into it
T11: Simas (me) is asking what is your market share and how do you develop your rubbers in cooperation with ESN?
R.B: that's too sensitive info and we don't disclose our manufacturers
T11: do top level pro players play with the same equipment as it is sold to other?
R.B: yes. We take extra step to select the equipment to be as consistent as possible (sponge hardness, ect..), but in principle, yes, it is the same
T11: should they make boosters legal?
R.B: no
T11: Even it's very hard to control the usage?
R.B: We should develop measures to control it better
T11: are you personally as CEO involved in the produt design
R.B: yes, quite a lot
