Your limited buy the f5 ratio to a 35mm EP so go with the GSO 68 deg 30mm SV 2".
I have the 40 mm (see review section) and it works great in my f6 and O.K. in a mates f5 , but exit pupil comes into play at f5.
I have tried the GSO 30mm and although it is a capable EP I went with the 30mm 80deg Andrews EP in my f6 , but you might find at f5 the outer field bothersome , so stick with the GSO 30mm.
Ask Iceman what his thoughts are on the Andrews 30mm 80 deg as he has mine at the moment to try it out in his f5 .
Try the GSO barlow with the 30mm to give you a comfortable 15mm. The GSO barlows are pretty dam good as well , for the price.
