I know this is a touchy subject for many, for some its like Ford against Chevy. But what blades are really the best for St. Augustine and similar type broad leaf grasses? What are the true advantages and disadvanteges of each? I need something that can handle dew and light rain, mainly mulch but sometimes I have to bag and dont want to have to change blades for one job only to change back afterwards. I run a 21" 6 1/2 HP Toro & a 36" Scag. Thanks for your help.
