Removing the idlers can only do you good, regardless of wearing out. Reduces complexity and weight. If you have to keep them, that makes sense, but I would remove them if at all possible.
What are you guys moving away from belts for? The epitome of flipped-cim gearboxes (192 in 2014) used belts for their first stage and it reportedly went swimmingly. Saves a lot of weight and space in these things IME.

I might be completely wrong about my team and belts, but we've been using belts for a while on our DT, and this offseason we're experimenting with chain DTs.

I mean... this only applies to the chassis, so perhaps I would attempt a belt system for the first stage. However, I'm using a large ratio for that stage, so I'm not even sure if there are the right pulleys for my configuration.

-Is there an online store that specializes in pulleys? It's been a while since I last been there, and my memory is fading away... -_-
-Also, is it possible to make your own pulleys? If so, is there a link to how to do that?
