Why combine the two? Do you know that SpeedZone has carfentrazone (ai in Quicksilver) already in it? What rates are you applying?
Sounds like a lot of carfentrazone. I would be concerned about off-target injury.
Speedzone also has wind speed restrictions that Celsius and Dismiss do not. 10 mph is a low cap and I wouldn't want to deal with any fines.
