I would be willing to pay a bit extra, and do with some negligible decrease in pedaling efficiency if it meant far fewer or no more broken spokes on the freewheel side. I am going to have to tie in to those web sites and do more reading on the subject, which I definitely will do.
Do you have a problem with broken spokes or are just concerned about the possibility? Decades ago, in the days of plated or galvanized steel spokes, broken spokes were fairly common. Now with stainless steel spokes and a proper wheel build, broken spokes are very rare, even with 32 spoke wheels and fairly heavy riders.
The broke spokes I've ever encounter were on the rear wheel of an '85 Bridgestone 400. The wheels were 36H, 27" Arya rims with 14 ga straight cadmium plated spokes laced 4X. I.e. in concept, a very rugged build. They began to break on the drive side at about 8500 miles. Now, the factory tension may have been inadequate too which can be a major contributor.
Since then I've had wheels with DT or Wheelsmith 14 ga., 14/15/14 db or 14/17/14 db stainless steel spokes, all 32H, laced 3x in 27", 700c and 26" and NEVER broken a spoke on any of them in over 120,000 miles of riding. Several of these wheels had 30,000 miles on them when they were replaced due to rim cracking at the brake track or the rim getting too thin from brake wear to trust. My riding includes some pretty rough roads too so these wheels were never babied.
The point of this is to ask if you are over reacting to the possibility
of broken spokes or really have a problem with them. Properly built and tensioned wheels with modern spokes should be very durable and reliable.
