RBW, I did have the Plus 8 early lightweight centre lock alloys as I really liked the design. However I did have problems getting them off once they were tightened to what I understood to be the correct torque and left for a few months without the recommended regular removal and re-fit. At one point I couldn't remove them with a much longer pole than Rich uses and a pneumatic gun had to be used. I decided at that point against regular use and resorted to wires as I didn't want to find that a wheel couldn't be changed whilst out on the road touring at any time.
I can't comment on the safety issues but I understand from a number of conversations that the alloy nut (of different dimension to the standard nut used on the wires incidentally) used on the Aero alloys was later drilled to take a grub screw for retention purposes.
