I have used the G5's G6's and regular high lifts on my 60" Toro 3000. The G5 and G6 didn't have enough lift imo. So last week a decided to try something different on my left and center blades I ran G5's and my right blade (closest to discharge) I used a high lift blade. It worked very well, and will continue to use this. I side discharge some lawns and bag some and it really made a difference.
