I agree with B in the sense that you have to do what works best for you.

I keep the strop a bit looser than what I've seen on videos and what I've read. I've not rolled and edge or dulled it. I've played around with tight, taught, super loose, etc.....and this is what has given me the best edges and most consistent feel.

Start with what you see on the videos by AFDavis and hi_bud_gl. Then go from there.

Hope this helps a bit.
