Looking for an article/post about rewiring the ST coils for better balance

I can't remember if it was from a post on here, or an article on utterpower or somewhere else that talked about rewiring the ST generator heads that puts the coils at 180* separation instead of 90* to help with groaning from imbalance.  I can't seem to find it, does anyone remember where it was?
