You may have already seen these, but here are the threads for my build.
With the risers and extra elbows, I didn't have enough airflow with three 3/4" intakes for hot n fast cooks. Low n slo it did just fine. Solution for me was to install a single fourth intake, 1.25" without risers or elbows. That intake gets opened up for higher temp cooks.
