Teach Plain Hunt before Call Changes? The advantage of using the sim to "pace" a helper for the learner to follow is you know that the striking will be right, particularly coming off the front/back. The first time I did this with someone who was already PH-ing with the band, they were all over the place and they were astonished at how big the speed changes were supposed to be. That's because the rest of the band weren't doing it correctly either, and they had just learned what they saw...
I agree, ropesight and rhythm are two sides of the same coin, once I could strike in more or less the right place by "feel" then I had enough spare brain cells to look for the next bell, which helped me strike better - a virtuous circle.
I know a few experienced ringers who claim they can't hear their bell and ring solely by ropesight, but as soon as you put them on a sim they certainly can, because any mistakes are theirs. I think perhaps with real ringers it can be difficult to decide if it's you or the other guy who is out, on the sim it's only ever you.
With the sim, my learner gets an hour of dedicated practice every week, with a perfect band. It's not a substitute for ringing with a real (imperfect!) band but it's much easier to schedule, and I think regular shorter sessions are probably best for learning ringing motor skills. My view is that the using the sim means that when they do get to ring with a band they can make maximum use of the opportunity, which is more satisfying both for them and the other ringers. Using the sim is in effect physical homework
