[GRASS-user] Resampling best practises

Hi,

I have a series of raster maps at 20m resolution in Mercator projection that I need to amalgamate into one raster in a different projection (Lambert Conformal Conic), and at a lower resolution of 100m.

Is it better to resample to a lower resolution in the current Mercator projection, then reproject, or reproject at the current 20m resolution then resample to 100m?
