I use gator blades and have tested them cutting a few strips and then changing to conventional.
What I found was the gators make smaller clippings so they tend to disappear easier, but as they wear the sharp"finger" edges become dull and seem to be the same as regular blades.
After I sharpen my gator blades, I use a cutoff wheel to also sharpen the "fingers" on the blades and that helps restore the smaller blades of grass advantage.
As far as windrowing, no windrows, it blows out full coverage of the discharge area.
I live on a farm not better homes and garden cover page type of place.
The grass gets cut cause it grows, not my favorite 3-4 hour chore a week.
the deck is a 50C my 782
I really don't care what it looks like, I used to run cows on the place and my cutting was an hour @ most, now I retired and the cows are gone, so I cut the green stuff.
In the fall gators eliminate leaf raking, best thing since sex!
They chop the DRY leaves so fine they disappear, it don't get any better than that!
( I do block off the discharge chute with an old license plate)

Now that is my story and i'm sticking to it.
