I say keep it simple. Slick trick, muzzy , thunderhead etc.

I personally don't see any reason to add a mechanical element.

I personally use the nap nightmare which is now called thunderhead razor or edge. The edge blades are serrated and interchangeable with the old nightmares and new razor.

A simple muzzy has to be the best bang for the buck out there.

g5 montecs are good ones if you prefer sharpening rather than blade replacements.
