Update - Joes Espresso Blend - day 7 post-roast - This stuff is really really good.
The changes- I started yesterday trying to use the advice given to me by the young lady barista at Joes who said that this blend should be pulled as a normale and I worked with that yesterday using doses of about 17.45362 gm

rather then stuffing 18.5 gm into my basket as they do using the three group LM at Joes.
Given that I see less solids extracted from the coffees in this blend I decided to pull a shorter ~ 0.75- 1oz drink using the same dose and a bit tighter grind. WOW what a difference. The flavors were stratified and layered rather then muddied together and consisted of sweet cherry and chocolate. The spice tasted yesterday was gone. If I could continue to pull shots like this it will be a winner that I will go back to purchasing. My guess is that my Anita reacts differently then the LM at Joe's especially to dose and the conditions I finally settled on, slightly less coffee and a shorter pull, mimicked the LM as best possible.
I will also be buying more Guatemala Finca Maravilla green beans for my own blends and SO's.
