Filter points from LiDAR upon import to terrain model

Question

I have LiDAR of an irregular stone object that I'm attempting to bring into PowerGEOPAK as a terrain, using the "Create from Point Cloud" tool. It's working well, but my data needs cleaning up. In the process of importing, it is filtering out 90% of the original data, which seems fine. But I have many tiny spikes in the resulting surface. There are too many to clean up by hand (I've tried). Are there any parameters I can use during the import process that might smooth the surface, or at least remove isolated spikes? I'm also working with Leica to see if there is any way to clean it up in Cyclone before attempting this with GEOPAK. 
 Any advice would be helpful! 
 Thanks,

You might consider using some of the point cloud tools. For information about workflow involved I'd recommend posting the question to their forum.

Hi Frank, 
 I question if you've really reduced the point cloud by 90% using standard point cloud tools. I recommend getting Bentley Points Tools loaded on your machine. This software truly reduces the point cloud and you can easily edit the file after reduction. If your point clouds data is classified you can filter it using those classifications too. I struggled with Point Clouds until I started using this software.
