Okay, I feel kinda stupid asking this question, but is the best choice of Gobo size for use in a S4 (standard, not Jr)? I'm specing gobos for an upcoming show, and the venue has more than enough template holders of both sizes. I know that either A or B will work, but is one generally preferred over the other? Considering that the aperture of a S4 is 3" wide, I would guess that an A size pattern would have the best coverage, but I'm not sure.
