I agree that an 8mm, 13mm and 21mm EP set would make a good range of magnifications.
I can't see what the negative argument is about the Ethos 100 degree apparent FOV. Consider this... with the unaided eye, I look at a distant object ; my field of view is almost 180 degrees. However, the clearest point is the centre of the field of vision. To see any point off-centre as clearly, I must aim my eye(s) directly in that direction. It is no different for an eyepiece. Whether the apparent FOV is 60 degrees or 100 degrees, the clearest point is at centre. Your eye has to rotate off-centre to view other points as clearly. It's just that you have a larger panorama in the 100 degree EP.
