I'm currently looking at purchasing a Parabolic PLM Umbrella from Paul C Buff to use with Paul C Buff Einsteins. In doing my research, many users recommend ta specific speedring to mount the PLM on the strobe. Apparently proper placement gives the full parabolic effect. Ironically, Paul C Buff only recommends to mount it using the umbrella mount and doesn't sell a speedring.
Can anybody shed light on the necessity of this speedring? Will it really make that big of a difference?
