Tonight I used doubles for the first time. I used a high lift on the bottom and a gator on top and they seemed to work pretty well. I only mowed my own yard and it wasn't very long. Tomorrow I will get the full effect. I put them in the + pattern and just torqued them down. (No bracket). If there not exactly in the + pattern will that hurt anything? And does it matter what blade goes on top, the gator, or the high lift. Im using a 48in husqvarna with a 15hp kohler.
