Jerry, your experience with Soaring Eagle is why it looks like we will eliminate mag stripe differences. So far, no one has told us they want them listed. As for the Brass Ass cards, they are different. Very different. There is a big donkey and a small donkey. I think this is much different than the mag stripe situation. The donkey logo is definitely a design difference. Measure from the top of the "B" in the word Brass Ass to the bottom of the "C" in Cripple Creek. The small ass logo is 39mm tall. The Large ass is 44mm tall. I think this is a sizeable difference. However, You did point out a card that needed clarification. This is the type of constructive criticism that we hope to get. Your comment just made the next book better. Others who weigh in on these topics should keep that in mind. If one lacks something positive or constructive to say, sometimes it's best to keep quiet.
