Actually - I use the same eyepieces in both, as I'm too tight to buy a set for my refractors! You need enough of a range to give low to high power, and I've found eyepieces like my 17mm and 12mm nagler are both in the sweet spot for my 25"f5, 10"f4.5, 4"f15 and 4"f5 (OK it's 102mm, not 80!). Obviously the 4mm radian doesn't see a lot of use in the 25", but 4 to 5 eyepieces from 4mm to 22mm will definitely keep you out of trouble regardless of aperture and fl - although the magic 50x per inch limit for scopes above 4" is a fairly reasonable thing to keep in mind.
cheers,
Andrew.

Tell us your Scopes and we can help.
