I find fewer drivers to be better, so chose a ZWO guider to go with ZWO mains. If the pair does not work, there is usually a good chance that the main will not work by itself either, so reverting 1 driver allows things to work again.
Right now is a good example, where the new ASI camera SDK appears to be causing some problems for myself and others. Reverting to the previous version, and both cameras work again.

I currently guide with a 290MM Mini, and quite like it.
