Best to just accept what popotnik is saying, he has a very advanced knowledge of fw and the problem is not in language but in the relative levels of knowledge and understanding between him and us. Basically what he's saying boils down to that the fw of 34x0 and 35x0 is quite different to that of the closest 2013 equivalent models 24/25x7 & 3597.
