Nice, I'll go for end of boil then. Thanks for the replies!
Dave, not that I'm at the level to be tweaking others' recipes but I was going to switch out the Mosaic for all Nelson (if I can get it). I love Mosaic too but I've been wanting to brew an all-Nelson batch for a while now.
Sorry it won't be Mosaic-related but I'll still post my results! Who knows, my LHBS might not have Nelson and I'll have to use Mosaic. Either way, I'll let you guys know. Thanks again!
