Suthera....use mere mortals will probably never know. Even those who are on the inside of the class do not know...those who have contacts do not know...I doubt even PSA, GS, LP and BK know the full story even if you got them in to a room! Suffice to say it is a mess and damn well needs to be sorted out so we can get the lovely new sail that everyone is raving about (although I did read that it has been 7 years in development....). My own view is that the jury is still out on the top section issue (especially as it only seems to be the 'new' top sections that are bending easily, builder collusion I hear you say, wash your mouth out!).
