This is a very interesting thread. I had some troubles with the honey not flowing through my 600/400/200 micron strainers this year, I guess it was a little thicker than usual. I use two sets of them, each in the top of a 5 gallon bucket with a honey gate for bottling. I'm thinking of upgrading to three or four buckets, each with a stainless set and the plastic set. Perhaps with the 1000/500 stainless set, I can forgo the 600 micron sieve.
