I believe both Cyclones were spec’d as good for an 18t difference?
I've read about folks using them beyond that capacity frequently. Vintage Trek catalogs show them handling the chain over 28/42/52 cranksets. Same for the AR, which is also said to max out at 18t. It was put to the same duty by Trek.
If both those derailleurs work that much harder than SunTour claimed, then I would expect the Vx to impress as well.
