Please can you shine a bit more light on the peculiar new cut out shape? where is the clean shape. all corners and small steps confuse me.... so I guess it will confuse the water flow also? Why, for instance is the new shape stopped 1 cm before the real side cut out start making the rail in the last cm just not as clean as possible?
Maybey Jim Drake or Tiesda can give some inside flow explanation on this?
