generally, the longer the focal length of your scope, the bigger the mag difference is between any 2 given eyepiece F/Ls.
for example:
on a 600mm FL scope, the 5 and 8mm produce 120x and 75x respectively (diff = 45x) ,
on a 1250mm FL scope, the values are 250x and 156x (diff = 94x).
on a 2000mm FL scope, the values are 400x and 250x (diff = 150x).
overall the difference between 5 and 8mm is significant enough at all focal lengths to warrant having both.
