I have two iSpindels for sale. New, never used.
Both purchased on HBT. One from @cayde1001. I cannot remember from whom I purchased the other.
Both iSpindels- $75 shipped in the continental USA
Looks pretty good...
I might suggest going with 10.8 pounds of pils and then 1.1lbs of Munich (or Vienna). Or if you wanted, go 10.8 lbs pils, and .55lbs each of Vienna and Munich.
For hopping, the 15min addition would not be typical in Germany... I would move all of your hopping to no...
