Glad the sulfur aroma is almost gone, Dan! I have used 2124 in my Helles exclusively and it does throw off a lot of sulfur aroma when fermenting. Thinking on going to 34/70 the next time I make the beer so I don't have to make a huge starter.
Also, and I have posted a picture of this on the forum before, I use a copper tube with a bunch of holes drilled in it on the end of the transfer hose from the chiller to aerate the wort going into the fermenter. Despite smelling the sulfur during fermentation, I never notice it in the finished beer. so the copper probably helps although this is a nonscientific observation.
