weight scales of Fins and Boards

Hi all..
well i am looking around for a shortboard and decided to go with webbers "the one"..
now theres allways the question of size, weight, fin selection etc...
since i live in switzerland and dont have the means to go out and try things on a regular basis, i need to relay on other folks knowledge and scales put up by the producer...
so my general question is: when looking at scales - do i rather go with more potential up or down?
saying: i am around 67 kilogram and 183cm - do i take fins for the range of 55 - 70Kg or with the one from 65 - 80Kg..?
since you run into scales pretty much everywhere - board size i.e. - this question came up more often and what better place to bring it up...
thanks in advance!
