I don't know that anyone has tried those particular plugs, but the general concensus here is that the stock NGK B8ES (or D8EA) plugs work just fine.
I looked at the link, seems that most of those plugs range from about $8 to $18 each. I can get a set of B8ES plugs for just over $8.

I feel reluctant to buy anything for my vintage Japanese motorcycle that the SPEED Channel endorses. I would have to see some dyno test results that aren't done by the company selling these plugs before I pull the trigger on buying them.

Looks like BS! How does it produce 3 sparks for every time the igniter fires the plug? The igniter only fires the plug once, period.
It must have a capacitor built in that stores the initial spark signal and then releases the stored energy at 2 different pulses. So the initial spark would be less energy than the original style plugs.1978 Gs1085 compliments of Popy Yosh, Bandit 1200 wheels and front end, VM33 Smoothbores, Yosh exhaust, braced frame, ported polished head :cool:

I would rather trust my bike to a technician that reads the service manual than some backyardigan that THINKS HE KNOWS how to fix things.

To understand how the "ignitor" works, let's go back to the eariler systems that use points.
When the points are closed, electrical current flows from the battery, through the coil, through the points and back to the battery. The wire inside the coil is wrapped around an iron core, which sets up a magnetic field. When the points open, that magnetic field collapses, which induces an opposing current in the core. Since the circuit is open, it has nowhere to go, but there is another set of windings around the core that has over a thousand times as many windings and it will produce several tens of thousands of volts which are directed to the spark plugs.
The "ignitor" is only a set of transistors that replace the points. That's all. Nothing more. Nothing "magical". The "ignitor" does not "ignite" anything, it only interrupts current flow through the coil, just like the points. It's advantages are that they can handle more current (stronger magnetic field, bigger sparks), they can start current flow sooner to build up the magnetic field (points have to follow the cam back down to their closed position) and there are no moving parts to wear out or adjust. The disadvantage is that there is basically no repair, only replacement.
Back to your original statement: yes, the plugs only fire once, but it's not the ignitor that "fires" them.

My question is what about the gap/resistance? Do you run the risk of burning your system out using these plugs? (Electrical is really not my strong suite)

electricity will take the path of least resistance..
meaning only one of those prongs will produce a spark.. not all of 'em.

The benefit will depend largely on of poor the ignition and flame front is in the first place. The GS's and especially the TSCC 4V per cylinder engines are pretty good and probably benefit little.
I'll interject that I run the NGK Iridium plugs. The primary noticeable benefit is they seem to furn off faster if the flugs ever foul. This can occur if riding to high altitude.

Point is, the spark plug will fire only once per ignition cycle, not 3 times.1978 Gs1085 compliments of Popy Yosh, Bandit 1200 wheels and front end, VM33 Smoothbores, Yosh exhaust, braced frame, ported polished head :cool:

Reminds me of the old Spitfire Multi-spark HT leads (not sure if they are still available). It produced a series of 5 sparks per cycle and was said to improve all manner of things. I tried one on an ageing Audi Coupe I had at the time and though there was the slightest improvement it wasn't enough to convince me to use on any other vehicle i've owned since then.
As long as your standard issue plugs and leads are in good condition you're not going to notice any difference.

Smells like the old trick of drawing on coil reserve, to artificially increase the spark energy. How long the coil will last under the extra stress is anyone's guess, but the old trick worked well enough for long enough, but that was with older, bulkier coils and not today's pared-down to the nearest cent ones.
The really old trick was to use a shirt button in the HT conductor, and the spark was forced to jump across that, then the plug afterwards. The coil reserve was drawn on to make this work. That dates way, way back, probably to the Model T.---- Dave

I'd have to try those .. but you will need an excellent available coil voltage to 'jump' 2 or 3 series gaps
Brisk, Spark plugs, racing spark plugs, iridium spark plugs, platinum spark plugs, silver spark plugs, lgs spark plugs, evo spark plugs, performance, plasma spark plugs, best spark plugs, NGK, ignition, auto spark plugs, turbo spark plugs, nitrous spark plugs, super charger spark plugs, surface discharge, multi spark
Spark "travels" from the center electrode to the edge of the first conductive ring, uses the ring as a conductor, jumps out from the other edge of the first ring intot he edge of the second conductive ring, uses it as a conductor, and then the spark discharge "jumps out" into the spark plug shell (ground) to complete the secondary ignition circuit."
