I have used it. I find that all WTI seed is pretty PH sensitive, with the Extreme being the best of them in that regard. Not knowing the area size nor the amount of moisture...hill side or flat ...well drain or clay, it's difficult to give a good answer. the Tilth makes a difference especially for root development.
I will say this in order for lime to do it's job it needs to be incorporated into the soil. It also takes upwards of 6 mos to REALLY lower the PH.
