Double bevels are a fun way to play with sharpening, they provide a shortcut in honing process. I think if you have regular honing down why not play with the double bevel. A double bevel can be a real time saver especially when honing a worn out wedge with large bevels.
I have added two layers of tape to the razor for the polishing hone on a variety of hones and razors. I have found that with as little as five strokes on a fine hone on the double bevel can make a really great edge.
It is not a big deal to get rid of the double bevel with a 4k hone.
I do not use a double bevel on every razor but it is a fun thing to try every now and then. I am usually looking for something to hone so the extra work is not an issue with me.
