Rolf and Cheshirecatman, thank you very much for your valuable inputs. If I read correctly, the only thing that I really went against your suggestion is the prebend and also more spreaders rake. OK I will work around theese settings during the weekend and let you know if you don't mind.
now Rolf I need some clarification when you say the telltales demand a flatter sail; Is this means top telltales streaming aft and leech telltale 50% of the time acting up?
Cheshirecatman, is my way of checking the match between sail and mast is wright? If so, should it be the starting point to define the prebend that I need?
