Nicanor,
Sorry, I dont know anything about the coverstock on the Teal Pro. Not even sure if they used the same core as the regular Teal. I cant go and ask the guy I bought it from because he is no longer at the proshop. You might try asking someone at Lane#1 or asking some of the posters here who are close to Lane#1.
All I know is what I remember the proshop operator saying before and after I purchased it. He said it was a milder ball and I was under the impression that he only got the ball because he knew someone at Lane#1. I think it was a limited release ball, perhaps only for the pros.
I know that the ball was very controllable, I was able to find the pocket easily with the ball but had trouble carrying with it. It did not do well on heavy oil as you noted.
Hope you find the info you are looking for and I will keep on eye on this topic to learn for myself.
