I had good results interpolating 5m contours with v.surf.rst, but I spent some
time adjusting the parameters to get a smooth surface.
IMHO You have a too big region to make this kind of computation and to use that
resolution, later you will get more problens with the size of the data. Maybe
you can use a lower resolution for large maps and a better resolution for
specif areas of interest.

If you tell the final purpose of this work maybe we can find a better solution.
