So,although I purchased (and received) a set of the yellow and blue bushings so I could mix them, they barely fulfilled their task as bushings. They acted as a buffer between the baseplate and the hanger but they allowed practically no steering whatsoever. This evaluation is not even in the task of "hard turning" or carving, just gentle turning over a large radius; they could not do it. What doesn't seem clear (and wasn't clear to me) was that there is actually a tapered piece of aluminum that goes into the bushing's depth for about half the thickness of the bushing. Additionally, they are not nearly as tall as they appear in the photos. The basic problem is that the aluminum flange, which is supposed to act as an integrated washer, takes up far too much volume in the bushing cone, and thus restricts the entire purpose of bushings, which is to flex. Furthermore, having cone bushings is primarily to enhance "carviness" because the larger area is where the larger force is applied and the smaller area is where it dissipates. I think, to achieve the same range of motion with your trucks, you would need higher conical bushings, but that doesn't logistically work. SO,unfortunately, I opened them, and put them on to try out in the street, and now they're used and I cannot return them. However, I *have* heard that the double barrel bushings are good. Most likely, when I replace my need to replace my old charger bushings again, I will do so with some Venoms.
