As one may figure I have a question regarding Veritas marking gauge, so if you guys have any input don;t be shy 
Is it worth to get a dual marking gauge, or just a single one is fine? As far as I can see, the dual one does not have a micro adjuster feature, but is it something that is used a lot ( it seems to me that using some thickness reference blocks, like one from Veritas, will get you quiet precise dimensions for marking)? Does a dual marking one present something that is of a more value compared to micro adjuster? Another question is whether one needs a graduated marking (be it imperial or metric?) or its a nice feature to have but is rarely used due referencing against stock, etc?
Thank you for any input!
