v.surf.bspline, v.surf.idw and v.surf.rst are good for LiDAR and proven 
through various journal articles. I have found that v.surf.idw has as good 
results as these others with default parameters (only 2!) but is 10 times 
faster in processing. So if you don't have the time for v.surf.rst, idw may be 
the way to go for a quick or large map solution.
