The SLOC is the first razor i reach for in the morning. It is the most incredible value in the shaving world.Yes that's a great suggestion for a SS DOC.
I have the RazoRock SLOC and find that it provides smooth very close shaves without irritation for my face.
Recently I purchased the SS Ascension. Having used it just two times I found it to provide a very close shave (the adjustable feature was not used to increase blade gap) but it was scratchy. The fingers of the comb are not like their counterparts on the SLOC.
Personally I prefer the RR SLOC which of course is also much less expensive.
The ideal DOC razor would be as you suggest a SLOC but made in stainless steel.
