Weight has always been an adverse issue in brakes, especially the weight of the disk in being able to be clamped stopped. Also, it goes to unsprung weight on the front end to try to manage, more weight, less ability to handle the front end. So, now, we have had steel, aluminum carbon and other brake disk media, soe work, most don't work well.
In the early days, light weight brake disks really didn't exist, there was only one person doing anything with light disks, Harry Hunt did a flame sprayed coating to an aluminum disk, for Yamaha only. We tried all sorts of aluminum special cutting disks, with anodizing, another process called "Banodizing", name it, nothing worked well.
We, Steve and I, ended up doing something we should have got the rights to, we'd both be rich now from it. About this very time in 1972, we started to mimic the 1965 Porsche Can-Am car disk treatments, we drilled, in secrecy, 72, 1/2 inch holes in two stock street bike H2 disks, creating "Holy Disks". I have been told there are hundreds of reasons we drilled them. H2R's used stock street bike H2 brake disks on the front ends.
The ONLY reason was, the street bike disks weighed like 3 - 1/2 pounds each, and drilling them lost roughly 1/2 their WEIGHT. Consider that on the rear wheel, the factory did a large diameter, 10 - 1/2 inch steel disk, that actually weighed more than the Triumph TR4 car 8 inch diameter front disk we drilled and used instead.
Today, brakes and components are so very much better, those shown here are just plain NICE. But, my preference is much like the OP, I am a two, to single finger front brake puller, and, twin disks, set up with as much caliper piston area as I can find, is the way I am used to, and like.
To each, their own.
