I went with three and I bolted them on. They've held with no problems so I decided to leave 'em that way. The FEL stalls way before these #5 bolts ever gets anywhere near breaking.
I like the 3 hook setup as it allows for easily centering of the load. I've lited with the center only, the two outside only and with all three.
They've brought a whole new dimension to the FEL.
