I originally wanted to go with a 4-element SteppIR for aesthetics, 
but what convinced me ultimately had nothing to do with an antenna at 
all. It was CQWW-SSB a few years ago. Saturday night, 40m; the band 
was on fire and I had a good shot into Europe with 600W my dipole. 
All of a sudden my logging software froze, then the PC abruptly shut 
off. It took me four hours to repair the log and get the PC up and 
running again. Indeed, Mr. Murphy had come for a visit and brought 
all his luggage with him.

I see the idea of having that kind of circuitry and mechanical 
complexity 70' up, where I can't service it myself, plus one extra 
cable run, is engraved invitation for Mr. Murphy to come back for a 
longer stay--of course, at the least opportune time.

While I'm leery of the rivets giving way, from what I understand, if 
an element or two fails at a rivet, the antenna will still be sort-of 
usable, albeit with degraded performance. If a Stepper motor fails, 
the control line fails or worst of all, the berrylium-copper tape 
breaks, that's're either QRT or stuck on one frequency (hope 
you weren't listening to something on shortwave broadcast at 16 MHz 
at the time it pooched out!).

As Scotty said, the more complicated the plumbing, the easier it is 
to stop up the drain."

Besides, try to tri-feed a SteppIR!
