I was curious as well and I found these descriptions on Seyberts. It appears that they are both yellowish cue balls with the red Aramith Logo being the more technological advanced cue ball. They are about equally priced at around $20. I'd opt for the red Aramith Logo ball since it's more durable.
If it's Super Aramith Pro cue ball, it should weigh in at 5.9 ounces or 168 grams. The red circle balls I've seen, along with Jim Rempe training ball weigh in at 5.6 ounce. Super Pro are heavier ball set than the lower tier Aramith sets.
