I don't consider myself particularly susceptible to the rolling ball effect but several different examples of 8x30 and 8x42 SLC's of about 15 years ago practically made me seasick after a couple minutes of looking through them, especially the 8x30's.
A friend had some 8x32 Victory's about 10 years ago that had slight rolling ball effect to me, but was much worse for him. He ended up selling them.
