Read many threads on this forum about this 2 balls, and I realize that..
AI and SI will have the same amount of backends if both drilled the same, only that SI will have more length and AI have a earlier roll.
AI will be able to handle almost the same amount of oil as SI(maybe a little more for AI?) but SI will skid a little long if the oil pattern is long?
AI will also be able to handle carrydown while SI might hit light pockets?
Last but not least, AI is more of a strong arc, while SI is a true skid/flip ball! =)
Correct me if I'm wrong.
