11 packs would be the way to go. I’ve been through more than 3 and didn’t find what I was searching for. Hoping its in the F2’s where I already found my keeper.
Found this while doing some more research lately.
Kushy Blueberry Muffins 
He’s talking about his Bubbashine keeper but that’s exactly what my SSDD F2 #1 girl smells like. With the Sour Butter from the Appalachia coming in up front.

Blueberry butter kush muffins. That’s what I search for in the SSDD’s.
There’s sooo many sour stone fruits, cherries, chem/skunk/incense tones…
raspberries soaked in gas (That was the F2 #2 I just ran out… was mids) I don’t want any of that. Give me the Sour Butter + Blueberry Kush Muffins.
Basically, if you find a SSDD and it’s not buttered kushy blueberrry muffins, it’s not the right one.
