In my case, I don't like the heavier knobs so that I can spin them. I don't think that I have done that since the mid 1950's, when we got chased out of C&G Electronics in Tacoma for seeing who could spin the slide rule knobs hard enough to move the pointer all the way across the dial! Instead, I like the "feel" of the heavier knobs. It is easier to stop at just the right spot, and when the fingers move away from the knob it is more likely not to move. A moment of inertia thing. Probably, the more finger coordination, the less this matters. But, I did find that it was easier to tune my K1 with 150 Khz tuning range when I installed a K2 knob, reamed to 1/4 inch shaft size.
