Two things:

1. The precooked sweet potato chips retained their crunch better than the raw slices. After the chips had cooled for a couple of hours, the precooked chips were definitely crunchier.

2. Even though I rubbed oil over the trays, the banana chips stuck in places. So if you try this, be sure to oil every little spot; those banana chips are sticky. (No similar problem with the sweet potato chips.)
