I get it, the pumps and valves is something that is really important and we should not try to get ahead with what is really important. So why not just try to test it and also get into what is really good and that is for what its worth. So I do like this and I don't hesitate that this is the really good solution which I do like and the small inert valves have their future when going on and That is not what people like. Yes, I like this and why not just try get it harder then you have done before? Yes, I do believe that this is the best thing that can be done and therefore also winning.
