I have the Pro Spreader and the regular Spreader. Both feature the quick release head with the 180 degree swivel, the punch out, and the leash. The advantage to the pro spreader is the leash rope that runs around the back of the harness with the integrated leash release at the right side of the spreader. Very well built it seems and very easy to use. I will be cutting the plastic "post" tube off my chicken loop since it will now be getting in the way. I haven't played with the release yet, but plan to hang from the ceiling soon 6-12 inches off the floor and see how well the release works. It seems to not be very rigid, but rigid enough so that it won't release inadvertently in a wipeout or if you bump it with your hands.
I haven't ridden it yet, but when I do I will post a follow up.
