Update:
Two marzens, same recipe, different efficiencies, different mash methods, one sparged and one not, everything else the same...
Are now in bottles after just 14 days with the help of gelatin and ice. They look and taste a bit different..... one with a touch more haze, one with diacetyl and the other not. I'm hoping the diacetyl disappears with a few weeks of age as has been my experience in the past. One I feel also has a much richer malt flavor than the other. Final gravities were also quite different, 3 points from one another. Feel free to take guesses as to what's what; however, I shall most likely need to restructure this very confusing thread later anyway.
Cheers.
