Ive been drooling over this thread for a couple days. Props to you AG.
You seem to know your sours so...do you know the difference between sour d and headband? I thought the original was the AJ and it had a few different labels. Daywrecker, headband, original diesel......
I have never grown Headband, Daywrecker they say it is a cross I believe Chem 91 xMSS/nl but idk.
The original diesel is Chemdog aka 91.
I have grown 91, MSS and ecsd my feeling is ECSD is a cross of 91 x MSS by way of hermie, that is just MO.
I have grown Loompa Headband/underdog she very much reminds me of a ecsd OG kush cross
