I think it is pretty universally recognized that without filtration or centrifugation it is impossible to clear 34/70. But powderiness is part and parcel of what makes it such a good yeast, a quick, consistent, thorough fermenter that really cleans up after itself. I will stick with the yeast and continue to use coarse (6-7 micron) pad filtration. Not just for perfect clarity, I dont like the slight yeast flavor that remains if any is still in suspension. I've been filtering so long it's something I could do in my sleep, and I've evolved my process to practically eliminate O2 pickup (unless you ask BR and Big Monk.)
