Notes

Mash efficiency is usually higher - if staying in style is important, adjust grain bill.
Single infusion at 148-150 will work very well, too.
K-97 really seems to work best at just below 60 degrees.
Thick krausen for 2 weeks or more.
Raise temp day 10-14. Rack to secondary around day 21.
Should clear without cold-crash by day 28 and be ready to package.
