Rudolf, I am intrigued by this. How do you prevent flexing of the board from transferring stress onto the small surface mount resistors and cracking them or the solder joints? A V-groove flexes at quite a sharp angle. (by design). I guess some thing like this would never be used in anything but very stable controlled environments. Actually now that I think about it this stress is a problem also for the routed/break-off tab implementation but maybe the copper is a little more malleable than those ceramic resistors.
