My opinion is to use two products. Speedzone in your left hand and Drive in your right. You need two sprayers of course. I am still waiting for someone to invent a sprayer capable of spraying two different products. Why spray broadleaf chemical on crabgrass, and crabgrass killer on broadleaves?
Also you may be able to cheat just a bit on the minimal time limits before seeding.
Last August I tried seeding after spraying with Lesco Eliminate (like Horsepower).
I found that the new seed did Ok if sown after 72 hours.
