I am going take the decision out of the hands of both UA and AS. I will be reaching out to all the college coaches that both events say will be there and see which event they are attending. They can’t be at both events unless the send separate staff. You want to be at the event the decision maker it attending. Find out what event they are choosing to spend their time.
This way you don’t have to waste your time and money trying out for both. UA seems to be full of evaluator politics and AS is said to be evaluated by professional independent and college coaches...no club coaches.
If college coaches are willing to evaluate a try out they are more apt to go to the event. Good luck!
