Yes, I most often just use one stone: Belgian yellow coticule - for all but serious bevel setting it works well enough given time. For edge maintenance it's certainly all I use and it works well enough. I do use a 1k hone for bevel setting very neglected ebay razors since the coticule isn't well suited to that use IMO.

I could ditch all my other gear and get by fine with just the yellow coticule - but that's no fun! For this reason I also own 1k 3k 5k 8k and 10k hones, an unidentified natural stone that puts a seriously sharp final edge on a blade, as well as a couple of pasted strops. It doesn't have to be complicated - i would have thought a 4k/8k combo hone would do everything you need; with the exception of restoration work, where a 1k hone is well worth having.
