Steve and I have agreed to disagree on the need for additional rivets.  I 
have not had anything even approaching an element rivet failure in 5 years 
with 3 force12 antennas.

In my limited experience, anything that breaks up the smooth surface of the 
elements, such as bolts or (gasp) tubing clamps, displays an almost magical 
ability to latch onto the nearest guy wire or tag line during installation.
