The best wheel to use are the dish rims and preferably made of some durable material that IS NOT HARD. I've had some dish wheels made of hard plastic that shatterred as soon as it touched anything.

In fact nowadays, the choice of rims is no longer an issue because most people like me buy the premounted Sorex or equal and they're all mounted on some type of dish wheel that will fit the E4 with no problems.
