I hate fluted bolts, like lipstick on a Pig! Love timed bolts! If you want to make your bolt feel smoother, put some SLIP 2000 ON IT! SLIP 2000 makes a bolt feel like it is working on roller bearings.
The flutes act like a catch all for debris, and if not cleaned on a regular basis, can and will bind up a high quality trigger. All the custom actions I own have fluted bolts.
Gun cases in the back of a truck are often left unzipped or unlocked, they collect dirt, then the dirt gets transferred to the action area, thus the saga begins.
