That mix of Acclaim and Horsepower sounds like a good MSMA replacement in cool season grasses. Gets both grassy and broadleaf weeds.

They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.
Benjamin Franklin 1775
Sell not virtue to purchase wealth, nor Liberty to purchase power.
