In my 3000mm FL scope I use the 7XW, 10XW, Ethos, 20XW and 30XW most. Basically the 30XW lives in my focuser on DSO nights (gives circa 40' field) and then I go shorter if I need more mag.
The 31mm Nagler is a good alternative to the 30XW though, in comparisons I like the XW more for optically quality but the Nagler does have a wider and more immersive field.
