AODE performance build~what fluid to run

I got my trans back transgo shiftkit alto clutches, seals, all new hard parts, TCI converter (saturdaynight special 600rpm stall speed higher than stock) what fluid should i run in it? i can get a case of wolfshead synthetic thru my shop 12 quarts for 44 dollars...mobil 1 is 120 dollars for 12. What you think?

he says castrol or penzoil or any quality oil thats merconV or even synthetic is great. But im a little nervous mobil 1 says its not for use in CVT transmissions and MERCON V approved. My wolfshead synthetic is also Mercon V approved, however its "super universal" and says it works in CVT trannies. I wonder what the difference is. Are all synthetic ATFS similar?
