Just a thought, but if some bikes bother you and the Sportster (!) and others doesn't, maybe it's not a vibration issue. Maybe it's a bike's handlebar length, angle, or height? Try the different bikes and pay close attention to your arm/wrist angle when riding. Apologies if I'm stating what you already are aware of.
On the subject of bar end weights, I do not understand them at all. I went on a 500 mile weekend trip last year on a BMW CLC, and about 100 miles into the trip on an interstate, I noticed that my left end weight was gone. I was all sorts of worried, imagining terrible vibes and handlebar wobbling for the next 3 days. The bottom line was, I never even felt or noticed anything.
