with the 4 man hide there is a space or "area" between the drivers cokpit and the second cokpit. That is where the rounded grab bar goes. On a 3 man, that "space or area" is the center bench. This leaves no room to do that. So we go with a single grab bar. If you put the female posts down in the cokpit with the driver, you will hit your elbows on it coming up to shoot. So, there is a small area over on the side just big enough for one post to go thru, hence the single grab bar.
